Why doesnât gastric juice digest the inside of the stomach?
arlik [135]
The inside of a stomach is coated with a lining that protects it.
This lining is made up of cells called epithelial cells. They coat the stomach with a mucus that neutralizes the acid.

The mucus contains bi-carbonate (a base), similar to baking soda.
Acid + Base = water and salt
