Digestion Process

Life journey of a hollo devise! My recoil devise consists of bread, butter and sliced beef. The prep are will be bitten by the front teeth in our mouth; these be know as the incisor teeth. The sandwich will begin to be broken polish by the teeth and jaws crushing and travail the aliment. The contents of the sandwich be indeed mixed with saliva to moisten it and to make it easier to swallow. The sandwich is formed into a bolus and the patois pushes the bolus to the back of the throat and and so it is swallowed. The saliva contains an enzyme called amylase which check outs down restrain (the bread) into sugars. The sandwich headeres down the gorge and after 3-6 seconds of leaving the mouth, the sustenance will reach the persist by the involuntary trouble like respectable 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 wherefore mixed with stomachic juices and the muscular walls of the stomach churn the contents into a watery called chyme. The stomachic juices contain mucus which moistens the food, they to a fault contain the enzyme pepsin and hydrochloric nutcase 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 thence enters the piffling intestine. In the humbled intestine chyme is mixed with a digestive juice from the pancreas called pancreatic juice. Bile, which is made in the liver, is as well as mixed with chyme. The bile helps lipase break down fats (butter and type of the 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 consort into the blood stream. The villi are part of the intestinal wall and ripening the area for absorption and so therefore they speed up the absorption of nutrients.
