Question

what happens if mucus is not secreated in our stomach ?

Answer 1

The alkaline mucous layers protects epithelial cells of stomach wall against enzymes and acids in the gastric lumen.
If mucous is not secreated by the gastric gland then the hydrocloric acid secreated by the glands will digest or corrode the walls of the stomach.

HOPE IT HELPS

Answer 2

Hi friend,
The hydrochloric acid released by the gastric glands will start to corrode
(or eat) the walls of the stomach.
Hope this helps. . . Cheers. . . .
