Digestion Process

Life journey of a hollo sandwich! My sound off 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 munch 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 vocabulary pushes the bolus to the back of the throat and accordingly it is swallowed. The saliva contains an enzyme called amylase which breaks down change (the bread) into sugars. The sandwich headeres down the oesophagus and after 3-6 seconds of leaving the mouth, the fare will reach the stomach by the involuntary tizzy like tendinous 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 th en mixed with stomachic juices and the muscular walls of the stomach churn the contents into a watery called chyme. The stomachal juices contain mucus which moistens the food, they to a fault contain the enzyme pepsin and hydrochloric nutlike 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 likewise mixed with chyme. The bile helps lipase break down fats (butter and part of the beef) into roly-poly 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 swoon into the blood stream. The villi are part of the intestinal wall and emergence the area for absorption and so therefore they sp! eed up the absorption of nutrients.
