Answer 2

The stomach is involved in the initial absorption of nutrients from ingested food. The mouth and teeth break food into smaller pieces which aids digestion by increasing the surface area to volume ratio, but the the actual break down of food into something accessible for absorption takes place in the stomach where gastric acids and enzymes act on the food. The stomach lining secretes the gastric acid (mainly hydrochloric acid) which both hydrolyzes simple compounds and activates the peptic enzymes into their active forms.

Large proteins are broken into smaller proteins.

Answer 3

Food enters the stomach from the oesophagus/gullet through a ring of muscle called a sphincter. Acid and protease (an enzyme) are then secreted into the stomach to start protein digestion. The muscular wall of the stomach also moves to cause the food to become a liquid called chyme (this is pronounced as kime).
