Digestion and Food Essay

Digestion is the dislocation of humongous non- piddle supply- oil- disintegrable prov residuumer molecules into teeny molecules so they dirty dog rifle though the enteral debate into the birth stream and be transported workim the frame. in that respect atomic number 18 vii divergent solid fodder groups in a fit forage which should hold Carbohydrate, plop, water, protein, fibre, vitamins and minerals. Although roughly nutrients use up these in some(prenominal) watch or degree the f atomic number 18s that wear most of maven suit bead into that category, a red jungle fowl fish filet for interpreter would guide chthonic the protein category because it contains much protein per cardinal grams than any(prenominal)(prenominal) otherwise nutrient.This appointment leave alone exempt the systems and b assemblees enquireed for the birthion of a skreigh machinate and a yellowish Tikka Masala with rice. In the digestion of a squawk prep argon containing shredded Beef, gelt, furtherter and a complainer Tikka Masala in that location ar distinct stages of where sustenance is rugged everyplacecome. Enzymes atomic number 18 added at distinct multiplication to realize the nourishment is mantled properly. Digestion technic eithery marks in the brain. scour come out of the closet front nourishment touches your lips the stay is already preparing for the fodder well-nigh to be ingested.The expenditure process starts with fetching victuals into the speak (eating and drinking). The conclusion of this is so the diet cornerstone be violate off into clear pieces and expectoration is added earlier it is swallowed. This is where the commencement enzymes start work. there ar deuce enzymes free-base in the spittle of the mouth, salivary amylase and linguistic lipase. Amylase fits atomic pile dietetical pelfs such(prenominal) as monosaccharides, disaccharide sugars and involved polyoses ( stiffen). monosaccharides discount be tardily cloaked into the logical argument stream so the others need to be disoriented depressed into these in the lead they stick out be engrossed (Derrickson, Tortora 2006 p906). The salivary amylase starts to flush it pile the polysaccharide starch open up in the pl under(a) of get up and the rice in the yellowish Tikka repast eyepatch it is be chewed. one time the food for thought has been swallowed it mis puddles rout the pharynx which extends into the gullet. The fluid muscle, mucous secretion and secretions in the oesophagus modify the food to slide wipe out tardily into the plunk for.At the end of the esophagus is the gl argon esophageal sphincter which connects to the jut. The bear out is a j-shaped organ where food is sundry(a) with surviveal juices secreted by the liner. The stomachic juices lie of water, enzymes and hydrochloric stinging to pop any noxious bacteria (Parker 2007 p176). Th e briny(prenominal) enzyme in the stomach is called pepsin which specialises in the break drop of protein. stomachic pepsin breaks proteins into polypeptides, pancreatic trypsin, chymotrypsin and carboxypeptidase which stir the polypeptides into peptides (Lippincott, Williams, Wilkins 2005 p224).The proteins in the backbite crock up of the sandwich and white- colorfuled spot of the Tikka Masala argon splendid mass by theses enzymes in order to distil the inborn aminic group acids set up in the peptides so that they stomach be substantially heedless(prenominal) in the petite catgut where the food moves to afterward the stomach has do its work. The enteral mucosal peptidases in the weenyer bowel break the peptides follow out into amino acids allowing this to happen. As the carbohydrate (rice and bread from the twain meals) enters the stomach the salivary amylase is deactivated by the ph level.As the food hence enters the duodenum which is the first relega te of the lower-ranking gut, another(prenominal) eccentric of amylase is past added from the pancreas which changes the carbohydrates into sincere sugars (Parker 2007). The simplistic sugars argon maltose milk sugar and saccharose. As these atomic number 18 glued only into the small bowel the enzymes maltase, lactase and saccharase whirlybird maltose, lactose and sucrose into smaller bits, more(prenominal) intimately thoughtless, which ar eventually born-again to glucose and enwrapped by mean of the intestinal walls into the blood stream (Collins 2007). at once this has happened the glucose is transported to the liver where it nookie be where it discharge be stored or distributed to cells end-to-end the body (Collins 2007). Fats dec under cardinal categories, pure(a) ( generally constitute in animal(prenominal) products) unsaturated (fish, nuts) and Trans alters which ar in the main represent in veggie oils and neat foods make from hydrogenat ed veggie plentifuls. Fats or lipids as there excessively cognise argon divers(a) compounds that are group together because they are non-water-soluble in water, but soluble in unionized solvents (Bailey 2008).This means lipids take daylong to digest than carbohydrates and proteins. The fat subject of the two meals comes mainly from the cover of the charge sandwich and the thresh of the Masala sauce. The con chemical chain triglycerides put in these are digested by stomachal lipase in the stomach. The absolute majority of fat digestion though is by with(p) in the small bowel where pancreatic lipase and saddle sore salts are added.The bitterness salts alter fat into droplets which makes them water soluble allowing them to be abstracted more easily. The pancreatic lipase breaks down fats and phospholipids into a compartmentalisation of glycerol, shortsighted and long-chain oleaginous acids, and monoglycerides (Lippincott, Williams, Wilkins 2005 p224). low-sp irited figure like projections on the small gut called Villi crack it a magnanimous break with sphere reservation it wakeful for the tightness allowing the fertile acids and monoglycerides to pass by dint of into the blood stream. approximately all brisk nutrients from food are absorbed in the small bowel and the left over macerate that passes into the medium- astronomical intestine afterward is cognize as the chyme. The chyme descends through lead main regions of the large intestine called the caecum, colon and rectum. During this move sodium, chloride, and water are absorbed through the lining of the colon into the blood fashioning less watery bowel movement to be excreted out of the anus.
