What are the functions of gastric glands present in the wall of the stomach?
Gastric glands secrete hydrochloric acid, pepsin and mucus. They have following functions:
(a) Hydrochloric acid kills any germ which may be present in food. It makes the environment in the stomach acidic; which is essential for functioning of gastric enzyme.
(b) Pepsin digests protein.
(c) Mucus prevents the inner lining of stomach from getting damaged by hydrochloric acid.
