Digestion Process

Life journey of a hollo organize! My kick sandwich consists of bread, butter and sliced beef. The sandwich will be bitten by the front teeth in our mouth; these be known as the incisor teeth. The sandwich will begin to be broken down by the teeth and jaws crushing and mash the aliment. The contents of the sandwich are indeed mixed with saliva to moisten it and to make it easier to swallow. The sandwich is formed into a bolus and the bevel pushes the bolus to the back of the throat and so it is swallowed. The saliva contains an enzyme called amylase which breaks down cumber (the bread) into sugars. The sandwich headeres down the oesophagus and after 3-6 seconds of leaving the mouth, the viands will reach the stomach by the involuntary charge up like sizable contractions, known as peristalsis. The epiglottis stops some(prenominal) of the sandwich entering the trachea by covering the windpipe hole. In the stomach the sandwich is churched and then mixed with stomachic juices and the muscular walls of the stomach churn the contents into a watery called chyme. The gastric juices contain mucus which moistens the food, they to a fault contain the enzyme pepsin and hydrochloric zany toons which pepsin needs to work effectively. The pepsin breaks down proteins (the beef) to peptides and amino acids.

Chyme is squirted from the stomach into the duodenum and then enters the small intestine. In the small intestine chyme is mixed with a digestive juice from the pancreas called pancreatic juice. Bile, which is made in the liver, is excessively mixed with chyme. The bile helps lipase break down fats (butter and part of t! he beef) into dipper acids and glycerol. The chyme is then pushed along the small intestine by peristalsis. As the chyme is digested, nutrients from the beef sandwich are released and absorbed through the villi and consider into the blood stream. The villi are part of the intestinal wall and maturement the area for absorption and so therefore they speed up the absorption of nutrients.
