Flashcards in The Digestive System - The Stomach (T2) Deck (1):
1

Describe in detail the stomach and the part it plays in the digestive system..

- carries out physical digestion, chemical digestion, storage and absorption of food

- food is held in the stomach for several hours, where protein digestion begins

- food is mixed with gastric juice containing hydrochloric acid and the enzymes pepsin and renin

- due to the hydrochloric acid, the stomachs pH is pH2

- the hydrochloric acid helps to begin protein digestion and it kills many harmful micro-organisms that may have been swallowed with the food

- the enzymes pepsin and renin work best at pH2

- once food has been chemically digested it is churned to form a liquid called chyme, which then enters the 'duodenum' (the first part of the small intestine)
