Does Third Cinema Still Exist or Has Already Died Essay

Does Third Cinema Still Exist or Has Already Died - Essay Example The term ‘Third Cinema’ was coined by in the 1960s by two filmmakers from Argentina: Fernando Solanas and Octavio Getino. In 1968, after jointly directing a film: La Hora de los Hornos (Hour of the Furnaces), Solanas and Getino wrote their manifesto known as hacia un tercer cine (towards a third cinema). There the authors had identified three categories of cinema: the First, the Second and the Third World Cinema. The Third Cinema is a form of opposition to the film making institutions of the dominating nations of the world. For this reason, it has also been described as ‘militant cinema’. The Third Cinema is defined by its director’s conception of the world. It is not determined by the genre of the film or any particular political viewpoint expressed by the cinema. This kind of cinema first flourished in the 1960s. This was precisely the time when many colonized countries were rising in protest in the form of their National Liberalization Struggle aga inst their western colonial powers. During this period, a group of film makers from the third world countries started making a new king of cinema. These were dynamic and politically stimulating films that represented the way of life and the political resistance in these less developed nations. Though these films were made on a variety of different themes, they were very different from contemporary western cinema. The directors of the Third Cinema wanted to provide expressions to the dissatisfied citizens of the third world countries who were already voicing their opinions on the economic and political exploitations of the western powers. Third Cinema provided the platform where people were allowed to argue, struggle and make experimental films which were a contrast to the usual entertaining cinema that was popular around the world. Solanos and Getino in their manifesto (1969) stated: â€Å"In the dependent countries, third cinema is a cinema of decolonization, which expresses the w ill to national liberation, anti-mythic, anti-racist, anti-bourgeois and popular†.              Ã‚

Mockery in Order - Essay Example Therefore, the development of control structures is useful in maintaining order as well as enforcing discouraging protocols. The establishment of order has its own draw backs which are useful in the creation of controls that are useful in the maintenance of orderliness in the society. The reduction of freedom of choice to a restricted module or activity is the principal drawback of order creation. In a bid to create uniformity and orderliness in society, there is the creation of laws, rules, and regulations which are useful for the development of the systematic way. Military personnel are easily identified because of the set of the uniform they wear; the same applies to police service and school going children. Some of the personnel may view the uniform as an infringement on rights to dress as they wish which is the paradox of order. According to Barthes, the infringement of one's rights in the army through uniforms and the set of rules is a mockery to order (Barthes 40). He refers to submission in the army as fanatic and a blind act (Barthes 40). Think of students in uniform! Uniform gives an impression of equity and order in school, but does it mean that they love wearing it? A clear no. Some of the students will always abuse the uniform. As a result, dressing chords are implemented to enforce order of which later results to strikes and the so called â€Å"cases of indiscipline†. What a mockery of order! The students feel that the order created infringes their rights and forces them to adopt what they cannot live to. In a football match, the separation of the two groups of fans and supporters help in the creation of order. Imagine, that there was no separation between the groups. What could be the consequence of such an action? There would be strife and fighting within the group leading to disharmony and strife. The separation of the groups leads to the creation of order in the match. The separation is a creation of that reduces or limits freedom of movement between the two groups. In the real sense, human beings need to interact with each other, to enjoy freedom of movement. This privilege is lost in order for the order to exist in the match. The existence of a physical barrier separating the two groups is obviously an infringement on the right for movement and association that is accorded to all human beings. Despite the success of the physical barrier, there are still problems facing maintenance of order in situations such as play interruption as a result of pitch invasion by supporters as wi tnessed in matches in Italian and Russian football leagues. Additionally fans may clash in the street with some fans obtaining injures or even death in the street confrontation. The solution to the problem has always been the designation of routes to reduce meeting of the two supporter groups. The route designation minimizes freedom and association movements. The restriction of movement and association is the price of order creation; thus, it creates a scenario in order to gain publicity, and show a need for order creation. According to the chaos theory, in order for the order to be created disorder must first exist and vice versa. The creation of order, is based on, the drive to make an organised structure from, a disorganised state. The creation and innovation experienced in the world is as a result of need for order in all spheres of life. It is vital to state that the need for order

This implies that its tax liability would be reduced, thus making the total liabilities to reduce resulting to higher profits. Companies in various industries have embarked on investing in greener brands in a short run even though it is expensive. The collaboration between finance and operations departments at Method may result to the Method pursuing greener activities that are costly in the short run. It is vital to note that businesses should have long terms perspectives such as increased customers, going global and product diversification among others. Such perspectives can be attained by looking at the current situation. For example, Method can introduce greener household brand that is expensive. Once it starts to advertise the brand and the government as well as customers notice that such product does not cause harm to the environment, it may be highly demanded in the international market in the next few years. This will definitely increase the company sales and improve its image in the global market where competition is very stiff. The same way, a greener car may be expensive for example if Method dec ides to acquire around 10 cars. However, the government may after some time offset the company corporate tax with the Method’s carbon footprint (Gillenwater 16). This will result to low liability and high profit for Method. The increased demand for household products has resulted to stiff competition among the firms in the industry. The companies have come up with different strategies in addition reducing prices. I think also other household companies just like Method are beginning to realize how green products can improve their financial conditions. For example, some companies have introduced initiatives

Buyer behaviour - Essay Example The brand was also listed as the #1 company in the world by Forbes.com in June 2012. The rankings were based upon aspects such as people’s willingness to buy, recommend, work for, and invest in a company which is 60% driven by the perceptions of the company and only 40% by the perceptions of their products. The Target Audience/Market Segment: The ad, in this context, is designed for the market segment of an elite upper class that touts trendy styles and exquisite tastes as the marks of their identity, as can be evidenced from the lady’s appearance and the driver’s initial introduction of her. The audience does not get to see her eyes, covered by dark sunglasses, but are told that the first thing one will notice about her is her â€Å"bright, blue eyes† which are usually covered up, but when one sees them â€Å"it’s worth it† (Most Expensive BMW Ad Ever-BMW, 2011). The ad subtly hints here that if the consumer notices the features of BMW, they will know the worth of it. The upper class consumer, who the ad targets, will definitely understand the cue. The target market segment is also likely to be educated, rich and willing to spend heavily on luxury items. Thus, the ad is appropriate in every context to the target consumer. Features and Benefits being Offered: BMW packs their engine with effective features and style according to customer segments. â€Å"The all new BMW 3 series sedan features the BMW Twin Power Turbo four-cylinder diesel engine of its predecessor, which has been honed for even greater fuel economy and lower emissions with no reduction in power output. The 2.0-litre four-cylinder engine is from the same family as the regular BMW 320d engine and shares the same all-aluminium crankcase, VNT turbocharger and latest-generation common rail direct injection† (BMW 3-Series (2012), 2005). Additional features like a slight reduction in maximum output rating, the rpm-reducing, friction-reduced powertrain des ign and an optimized aerodynamics package has helped BMW to bring down its CO2 emission to the lowest. It also comes with 5 rear view cameras to support complete driving safety. The safety measures provided include dual front airbags, side airbags and head protecting side curtains.The BMW 3-Series Sedan is also equipped with an Auto Start-Stop function, which analyses and automatically turns off the engine during short stops to save fuel. The BMW also features important safety measures such as antilock brakes (ABS), electronic stability control (ESC) and electronic brake force distribution (EBD). Intelligent seat belt reminders are also fitted to all seats as a measure of safety and comfort. In the context of this ad, the features of the product remains emphasized throughout, right from its beginning. The lady explicitly expresses that she is done with black, thus connoting to the appeal of the change to white. The car’s manoeuvrability becomes evident when it glides through the mob whereas the car that follows gets trapped. The lady scolds the driver for his lack of pace as she wants to lose her trailing bodyguards. He picks up speed, takes several abrupt twists, turn and swerves that throw the lady around to all nukes and corners of the car but she remains in good shape. Thus, the ad, through the action unfolding before the audience’s eyes, illustrates the features of the car in terms of visual appeal, speed, manoeuvrability, comfort

Deadly Unna Film Essay Example for Free

Deadly Unna Film Essay Australian Rules A comparative review by Anita Jetnikoff (QUT) for Australian Screen Education. Published as: Jetnikoff, Anita (2003) Australian Rules: a comparative review. Australian Screen Education(30):36-38. The title may mislead some viewers, as this is not a film about a football code, anymore than Bend it with Beckham is about soccer. This powerful, brave and rather brutal feature is the debut of Paul Goldman, who co-wrote the screenplay with the novelist Phillip Gwynne. Both the storylines and characters from Gwynne’s awardwinning novel Deadly Unna? nd its sequel Nukkin Ya, have been combined in the film, which was commissioned by South Australian Film Corporation for the Adelaide Festival of Arts 2002, and caused a furore with the local Aboriginal community. The film was screened after much deliberation over the objections against depictions of a character resembling a member of the Penninsular community. This certainly suggests collaboration with Indigenous communities could have been sought at earlier stages of the project. In my reading of the film, however, it is the white community who emerge the more brutal, bigoted and shameful. The Aboriginal community, on the other hand, represent solidarity, and sharing. The film was released and promoted by Palace, with the slogan ‘live by the rules play by the rules’. There is, however, an almost apartheid divide between the black [Nunga) and white [Goonya) communities in this film and the central character’s personal navigating between the two, means he must break unwritten rules. The film is based on aspects of two novels, the partly autobiographical novel Deadly Unna, and its sequel, Nukkin Ya, Nunga expressions for ‘Great hey’ and ‘See you later’. Both novels were easy to read and full of humour in spite of the serious subject matter of racism, interracial relationships, adolescent angst, death and revenge. The novels belong to the adolescent problem or coming-of-age genre and are being studied in secondary schools. The film has little of the novels’ lightness and the narrator’s ability to laugh at himself and his community’s foibles. This sometimes disturbing film’s tone is brutal, the landscape stark, sordid and in decay. Most of the characters occupying the saline, arid coastal town are nasty. The adult men are barflies, maggot breeders, fornicators and losers and the women are victims or sluts. This hopeless adult world offers nothing for the young in this fishing town. Viewers are invited to identify with the young, for whom hope lies in escape. The central figure of Blacky (Nathan Phillips), is an intelligent 14 year old caught between the literary world of his imagination and the literal world of his small towns’ bigotry. His mother, who encourages him to play football and to do well at school, is a battler, a victim of his father’s brutality. The dilapidated house the Black family occupy oozes poverty and neglect. These are white fringe dwellers. In the novel Blacky refers to what kind of chops the family will consume as indicative of the ‘pov metre’. They shop at the local op shop. Like many small rural Australian towns, this coastal community struggles to survive. The black and white communities in the region are divided, separated physically by a stretch of coastline, whites at the port and blacks at the point. Even the local pub segregates the Aboriginal drinkers from the white ones. The irony is that the local football team is only viable when the Aboriginal boys come over from the point to play. The sporting fixture allows the communities to merge, but the union stops there. Blacky crosses the racial divide to befriend Dumby Red (Luke Carroll) a talented Aboriginal Australian Rules Player from the Point and to romance Dumby’s sister Clarence (Lisa Flanagan). Whereas book built up the friendship through Blacky’s doubt and hesitation about Dumby, this is not dealt with in the film. The film opens with the two characters already mates, sitting together in the dilapidated shed of the red dirt football field, commiserating over the ineffectiveness of their coach, Arks (Kevin Harrington). Dumby’s spectacular football prowess has been spotted by a city talent scout, which sets up the need for him to win best Player in the final against a much stronger team. A contract to a city football team would mean a possible escape from the bigotry and emptiness of the Penninsular—his chance to be a sporting success. Blacky finds himself an unwitting hero and awarded best team man for winning the premiership game. He unwittingly collides with the toughest star player on the opposing team and is knocked unconscious, along with his gigantic opponent. The shooting sequences of the match were not especially riveting, but this was in keeping with the importance of the game to the story. The film is not about winning or losing, but the personal integrity of the play or the journey in the ongoing process of discovering identity. The medal for ‘Best on the Ground’, rightly belonged to Dumby Red. His ticket out of the hopeless community, however, was denied to him, because rather than kicking a sure goal, he had passed a ball to a cousin who had not handled the ball all day. The cultural code of sharing was stronger than the competitive need to win. In the film, the loss of the award to the coach’s son paves the way for Dumby’s tragic demise. He joins Pretty (Tony Briggs) in an armed robbery of the pub, perhaps to extract an alternative prize to the one he’d been denied. The publican, Mac, laid out in a drunken stupor on the pool table, is beaten even more senseless by Pretty. The noise rouses Blacky’s father (Simon Westaway) who shoots and kills his son’s friend Dumby Red in revenge for the publican’s beating. In the novel the publican was the murderer, but the film’s central villain is Blacky’s father, Bob, who represents fear, loathing and menace. His violent rages left his own family in fear of him. In one memorable scene they escape his menacing torment of their mother behind closed doors by escaping through the window and sleeping in the chicken coop. The feeling is that this experience was not new to them. Blacky is torn in the novel between his initial attraction to Clarence in Deadly Unna, which he conceals from his white ‘friends’ in order to attract the attention of a rich white ‘camper’ girl. In the sequel this relationship between Blacky and Clarence and Blacky and his father represent two kinds of coming of age. His masculinity is tested early on in a storm at sea and later when he was caught in the shed stealing paint to cover a racist slogan in the local boatshed. His intelligence means little to his father, and his good grades and scholarship to Kings College in Adelaide are ignored. In the sequel Nukkin Ya, the filial relationship seems almost mended when his father takes on the renovation of a ‘windjammer’ to bring potential tourism to the town. His father’s project becomes obsessive at the expense of putting food on the family’s table, but the male relationship seems to be temporarily repaired along with the boat, which becomes symbolic of rebuilding strength, unity and hope around the fantasy of the future. In the novels we experience Blacky’s angst at discovering his father’s infidelity to his mother. Blacky and his friend Pickles, stumble upon their adulterous fathers visiting the Aboriginal women at the point. The irony of this is that the entire community seemed set gainst the burgeoning love relationship between Blacky and Dumby’s sister Clarence. The fact that the cross-race relationship of the father is not dealt with in the film makes his violent reaction to finding Clarence innocently sleeping alongside Blacky in his bedroom connected more with his hatred of Aboriginal people, than it is to do with his guilt over murdering Dumby Red. It is a response reduced to racism alone, rather than his own guilt and hypocrisy, which in the novels is built up subtly through the two volumes. The antagonist in the second novel, having moved away from the father, is embodied by the figure of Lovely (Pretty, in the film) who menaces Blacky over his relationship with Clarence. Lovely sports a hate tattoo on his fingers and is a violent instigator in both book and film. The disclosure of the white men’s infidelity at the expense of the black women, who remain nameless and faceless, leads to the climax of the second novel. The boat is set alight, which symbolizes the death of the relationships between Blacky and his father and his community. Lovely is framed, Blacky absolves Lovely in court by taking the blame, but Pickles (Tom Budge ) was the real arsonist. This false confession, leads to Blacky becoming a cipher in his own town, where boats and the sea are peoples workplaces. He becomes a ‘boat burner’ in the cultural imaginary and is forced to leave. In the film this purging is less powerful and seems to emerge from some kind of corporate malice rather than revenge. Pickles manically sets alight rival maggot breeder Darcy’s breeding drums, which has less symbolic poignancy than the boat burning in the novel. Blacky’s central challenge in the film is to reaffirm his masculinity by standing up to his father, through the relationship with Clarence. Blacky is constructed by his father as a ‘gutless wonder. ’ Blacky’s painful journey to manhood, is much harsher in the film than the book. In the novel the father is a violent adulterer, but in the film, he kills Blacky’s best friend. Blacky’s attendance at Dumby’s funeral represents a betrayal of familial solidarity in the eyes of the father. The relationship was not strong enough however, for Blacky to take his father’s side. At this point, Blacky abdicates from identifying with his father. He has begun to flee the emasculated self constructed by his father, towards a more potent, sexual self, embodied by his attraction and identification with the other through the literal ‘body’ of Dumby and the physical, sexual body of Clarence. What is morally worrisome is that the father, who both Blacky and the viewer see as a murderer, continues to live in the community with impugnity, the ‘common sense’ gap we fill is that he claims he shot Dumby in selfdefense. Blacky courageously resists his father’s imperative to stay away from the funeral. In the film’s powerful and moving climax, the battered, but united family in the background witnesses the final stand off between father and son. Blacky literally stands up to his father, not by competing in battle of fists, but resisting by sheer will and strength of character. The father leaves in a vicious rage and we can’t help feeling that the family will be better off with him gone. The second novel Nukkin Ya begins with hope of Blacky taking a scholarship at Kings in Adelaide. His girlfriend Clarence achieves a scholarship to art school and Blacky has a reason to follow her. The film ends with the two young lovers romantically swimming in the clear waters, symbolically cleansing themselves of the grime and grease of prejudice, which had tainted their relationship until that point. The film treats the romance in a much lighter way than the books. There is no stand off between the characters; in fact Clarence becomes Blacky’s bridge between the two cultures. In the film it is Clarence who stands up to Bob Black in Blacky’s bedroom with dignity and silent resistance. Lisa Flanagan’s performance was elegant and dignified. It was Clarence who gently cut through the wall of hostility from the Nunga boys at her brother’s funeral- allowing Blacky to mourn his friend’s death. It was Clarence who understood Blacky’s poetic allusions to dying stars- these two are cosmically connected and there is an almost Shakespearean sense of their fate. The love scenes provide the film’s only softness and the resolution, although moving, is not sentimental. The young people must leave the still-divided community, to survive together.

Essential Anatomy and Physiology Components

Essential Anatomy and Physiology Components Mahbubul Alam Task 1 Most of the nutrients in the feed are large molecules that can not be directly absorbed in the gut due to their size or hydrophobicity. The digestive system is responsible for the reduction in the size of these molecules directly absorbable smaller units and the conversion of hydrophilic molecules with hydrophobic complexes. Proper operation of absorption and transport mechanisms is essential for the delivery of products of digestion in human body cells . An abnormality of one of these systems can cause malnutrition even in the presence of adequate nutrition . Functions of Digestive System The task of the digestive system is the physical and chemical breakdown of food. In addition, energy needed by the body , as well as raw materials for growth and repair of body structures come from the food and drink that ingerimos. In the digestion process are the following functions: Test food through the senses of smell and taste, food crushing , dissolution in water, food transport crushed decomposition of food into simple substances with the aid of digestive enzymes, absorption simple substances, and elimination of indigestible residues. Regulation of digestive functions Digestive functions traction and secretion are controlled by two main types of regulation: the nervous regulation and hormonal regulation . Neural Mechanisms Nervous regulation of motor and secretory phenomena uses two types of neural networks : a local system , the enteric nervous system and the autonomic nervous system (ANS ). Nerve receptors are sensitive to various stimuli : the chemical composition of the chime (acidity) , stretching (feeling of fullness ) , etc. . They send impulses to the muscle and secretory cells of the digestive tract via the enteric nervous system consists of the myenteric plexus and submucosal . Neurotransmission is nervous or chemical type ( enkephalins , somatostatin , serotonin, bombesin , neurotensin , etc. . ) .The ANS consists of two contingents of fibers : sympathetic fibers that run along blood vessels, and the parasympathetic fibers of the vagus nerve. These two contingents have antagonistic actions: roughly, sympathetic fibers are inhibitory while the parasympathetic fibers are excitatory . Structure Core Structures : Mouth, pharynx , esophagus , stomach thin intestine , Ano Associated structures : salivary glands ( three pairs ) , Pancreas , Liver, Gall Bladder ( with their associated ducts) , and Appendix. Process The substances that the body needs are absorbed from food , it passes through the digestive system. When chewing food, it is moistened by saliva. As food is sufficiently fragmented and wet mouth are pushed by the tongue into the pharynx and swallowed. The muscles in the walls of the esophagus contract and relax to cause movement in waves, known as peristalsis, which lowers food into the stomach. In this , mixed with acidic juices produced by the wall of the organ. These juices facilitate the fragmentation of food in even smaller particles , the muscles of the stomach wall also contract , and facilitating the greater fragmentation. Thereafter , they pass into the small intestine where certain products contained in the digestive juices , known enzymes continue the degradation of food in nutritional components which are absorbed by the blood through the walls of the small intestine. Leftover food particles , which are not digested in the small intestine pass into the large intestine where water is absorbed. The remaining food is a partially solid waste is gradually propelled along the large intestine and takes the form of feces reach the rectum. The depositions are stored in the terminal portion of the digestive tract and are then expelled through the anus. Anatomy The esophagus is a tube or membranous muscle that extends from the pharynx to the stomach. Incisors to cardia ( portion continues where the esophagus and stomach) there are about 40 cm. Esophagus begins at the neck, chest and traverses into the abdomen through the esophageal orifice diaphragm . Usually it is a virtual cavity ( ie that its walls are joined and only open when the bolus passes ) . Measure reaches the esophagus 25 cm and has a structure consisting of two layers of muscles which allow contraction and relaxation of the esophagus downward . These waves are called peristalsis and is causing the progress of food into the stomach. Its just a passage of the bolus , and is the union of different holes , oral , nasal , ear and larynx. Stomach: The stomach is an organ so that varies depending on the state of repletion (amount of nutritional content present in the gastric cavity) that is usually shaped J. It consists of several parts that are: fundus, body, antrum and pylorus. Its less extensive edge is called the lesser curvature and a larger curvature. The cardia is the boundary between the esophagus and stomach and pylorus is the boundary between the stomach and duodenum. In an individual measures approximately 25cm cardia to the pylorus and the transverse diameter is 12cm. To see what is inside the stomach click here. Small intestine: The small intestine begins at the pylorus and ends at the ileoceal valve, which is attached to the first part of the large intestine. Its length is variable and its size gradually decreases from its origin to the ileocecal valve. The duodenum, which is part of the small intestine, is about 25 to 30 cm in length, the small intestine consists of a proximal portion and a distal jejunum or the ileum, the boundary between the two portions is not very apparent. The duodenum joins the jejunum after 30cm from the pylorus. The jejunum-ileum is part of the small intestine that is characterized by relatively fixed ends: The first originates in the duodenum and the second is limited to the ileocecal valve and first portion of the blind. Its size decreases slowly but progressively towards the large intestine. The boundary between the jejunum and ileum is not noticeable. The small intestine villi has numerous surface increasing intestinal absorption of nutrients. Intestine: The large intestine . starts from the ileocecal valve in a blind pouch called from where the vermiform appendix and ends at the rectum . From the cecum to the rectum describes a series of curves , forming a frame in the center of the handles are yeyunoà ­leon . Its length is variable between 120 and 160 cm , and its size gradually reduces , being narrower in the region where it joins portion rectum or rectosigmoid junction, where the diameter is usually not exceed 3 cm , while the blind is 6 or 7 cm. After the blind , the second portion of the large intestine is called as ascending colon, with a length of 15cm , to give rise to the third portion which is the transverse colon with an average length of 50 cm , resulting in a fourth portion which is the descending colon 10cm in length. Finally differs sigmoid , colon rectum and anus . The rectum is the last part of the digestive tract. It is the continuation of the sigmoid colon and ends up opening up to the outside through the anal opening . Pancreas: Gland is intimately related to the duodenum, the excretory duct of the pancreas, which ends meet with the bile through the ampulla of Vater, their secretions areimportant in the digestion of food . Liver: The liver is the largest internal organ of the body weighs 1500 grams. It consists of two lobes. The bile ducts are the excretory ducts of the liver , bile for them is driven into the duodenum . normally get two channels: left and right , that converge together to form a single duct . the hepatic duct receives a finer duct, cystic duct coming from the gallbladder housed in the visceral side of liver. Meeting of the cystic duct and the hepatic bile duct , descending duodenum , into which together with the excretory duct of the pancreas is formed. The gallbladder is a reservoir musculomembranous shunted on the main bile duct. It contains about 50-60 cm3 of bile. Is oval or slightly pear-shaped , and its major diameter is about 8 to 10 cm . Spleen: The spleen , for its main functions should be considered an organ of the circulatory system. Its size depends on the amount of blood contained therein. Digestive Physiology The gastrointestinal tract is responsible for the digestion of the ingested food , so that they can be used by the body . The process of digestion begins in the mouth where food is covered by saliva , crushed and divided by the action of chewing and once formed the bolus swallowed . The stomach is not an essential organ for life, for though his removal in man and animals cause certain digestive disorders, not fundamentally affect health. In humans , the essential function of the stomach to reduce food to a semi-fluid mass of uniform consistency called chyme , which then passes into the duodenum . The stomach also acts as a temporary reservoir for the acid foods and their secretions , has some antibacterial action. The chyme passes the pylorus and enters the duodenum intervals where it is transformed by the secretions of the pancreas , small intestine and liver was continued digestion and absorption. Chyme is progressing through the small intestine until it reaches the large intestine. The ileocecal valve too fast hinders the emptying of the small intestine and prevents reflux of the contents of the large intestine to the small intestine. The main function of the large intestine is the formation , transport and disposal of feces. A very important function is to absorb water. In the cecum and ascending colon faeces are almost liquid and that is where the greatest amount of water and some dissolved substances are absorbed, but also in more distal regions ( rectum and sigmoid colon) liquids are absorbed. Digestion and absorption Digestion of food is effected by hydrolysis using digestive enzymes and cofactors such as hydrochloric acid or bile . Cofactors are also involved in the mechanisms of absorption. Enzymes are of 2 types: exoenzymes and endoenzymes. Digestive enzymes are exoenzymes mainly synthesized by specialized cells of the mouth, stomach , pancreas or small intestine and that are released in the digestive light to catalyze the hydrolysis of the food to the outside of the cell .The enzymes are endoenzymes localized on the membrane lipoproteins digestive mucosal cells . The connection to their substrate therefore when those latter penetrate into the cell. Ingested food are absorbed about 95%. The water , inorganic salts , monosaccharides , vitamins and alcohol are absorbed without change. As against , disaccharides , polysaccharides , lipids and proteins are to be transformed by hydrolysis into simpler components before being absorbed. Factors influencing the digestion Psychological factors: The appearance, smell and taste of food served modifies the emotional climate during the meal which influences the digestion of ingested food. Indeed , salivary secretions , gastric , etc. . and alter motility of the digestive tract . Emotions such as fear , anxiety or anxiety act via the hypothalamus and the autonomic nervous system affect digestion by reducing secretions , inhibition of peristalsis and increased sphincter tone . Bacterial action . The intestinal flora is a complex community with over 100 different species. At birth, the gastrointestinal tract is sterile, but many species rapidly colonize the digestive tract. Lactobacillus is the main bacteria flora until the child gets a varied diet . Then Escherichia coli dominant in the terminal ileum , and the anaerobic flora in the colon appears . However, the number of lactobacilli persist in subjects taking a normal diet. In the stomach , hydrochloric acid (HCl ) has a bactericidal action , which destroys most bacteria in the gastric acid chyme . In hyposà ©crà ©tion gastric cases, bacterial overgrowth can be responsible for gastritis resulting in inflammation of the mucosa. In the colon , bacterial action is more intense. It leads to the formation of gas (H2 , CO2 , CH4 , O2, NH3 , etc . ) , Acids ( lactic , acetic , etc . ) , And many other substances ( indoles , phenols , etc. . ) . The smell of feces is related to many of these components. The meal ingestion alters the fecal flora in very different ways depending on the individual . The ingestion of carbohydrate fermentation tends to increase while the increase of protein putrefaction . Effects of food preparation and meal composition . Cooking makes them more easily digestible : cooking meat relaxes connective tissue, facilitates chewing making it more accessible to digestive juices tissues. A heat load and composition equal meals low volume and more can be better digested than lavish meals . The chemical reactions during cooking alter food digestion . Acrolein produced by frying foods at elevated temperature, delays gastric emptying . Instead, meat extract ( bouillon ) stimulate digestion . Finally, there is a wide variation within and between individual sensitivity to food, their physical properties (temperature , acidity, etc. . ) That is frequently associated with the state of repletion of the digestive tract . Task 2 The Endocrine System and Its Working The endocrine system is a term for all the organs and tissues that produce hormones. They are distributed throughout the body and can show effects over long distances on: Growth Development Functions of many organs Coordination of metabolic processes The endocrine glands are organs, but who have no ducts, because they distribute their products directly into the blood or an autocrine or paracrine effect, however. Therefore, there is at this tissue with a dense network of blood capillaries with windowed endothelium. Exocrine gland secretions free to oppose it with their inner or outer surfaces: on the skin, on the wall of the stomach or in the pancreatic ducts. The hormone-producing tissue can be divided into three groups: Purely endocrine glands, used exclusively for the production of hormones; Exo-endocrine glands, in addition to the hormones produced other exocrine secretions; Certain non-glandular tissue such as the autonomic nerves, which also secrete hormone-like substances =neuro secretion Location and Function of 3 Endocrine Glands Thyroid Developmentally, the thyroid gland goes out of the intestinal epithelium of the pharynx bottom out on the tongue base. This gland stands at the beginning of the development through the ducts thyroglossus still with the floor of the mouth in combination and is located in front of the trachea after a descent. Anatomically, the thyroid gland is composed of two lobes, which are on an isthmus that is sometimes formed as a real pyramidal lobe, in conjunction. Without thyroid hormones cannot live. The thyroid hormonetriiodothyronine (T3) and thyroxin (T4) are iodized. They work in almost all body cells and stimulate there on the energy metabolism. The thyroid itself is in terms of a control system by the hypothalamic hormone TRH (TSH-releasing hormone), and originating from the pituitary TSH (thyroid-stimulating hormone) in their function regulated (Hiller-Sturmhofel, 1998). Endocrine Pancreas The pancreas is an exo-endocrine organ by both digestive juices into the duodenum and releases hormones into the bloodstream. The endocrine portion, the islets of Langerhans are localized mainly in the pancreatic and stand out due to their brighter appearance. They secrete their secretions directly into the bloodstream. A distinction is to effect different types of cells: B cells: 60-80%, are used to produce insulin A cells: approximately 20%, and are therefore intended to antagonist to insulin D cells: about 2% serve to have an inhibitory effect on the A-and B-cells as well as on the exocrine pancreas. PP cells (pancreatic polypeptide): ~1-2% and inhibit pancreatic exocrine These islands consist of a net-like organization of several thousand epithelial cells arranged in groups and are crossed by numerous capillaries with windowed endothelium (Carter, n.d.) Pituitary The pituitary gland is located at the underside of the brain and is composed of three parts. In contrast, the anterior pituitary produces own hormones. The activity of its cells is determined by complex humeral and neural mechanisms regulated (= control hormones). It is above all the hypothalamic releasing and release-inhibiting hormones that play an important role (Drake, 2010)
