Question

List the functions of the digestive system:walls of the stomach,hcl,mucus

Answer 1

These muscles allow the stomach to squeeze and churn the food during mechanical digestion. Powerfulhydrochloric acid in the stomach helps break down the bolus into a liquid called chyme. A thick mucus layer that lines the stomach walls prevents thestomach from digesting itself.

Answer 2

walls of stomach-partial digestion
hcl-sterilize the food
mucus- protect the cell lining
