Answer 2

If the stomach fails to protect itself from hydrochloric acid,i.e. due to the damage of the mucous membrane,it may lead to stomach ulcers or H. pylori.Simply, it's because of the mucous layer around the stomach, that prevents the strong acid, HCl to hurt our stomach. Not only this, if there were no mucous, the HCl would digest the protein present in the epithelial cells, so the stomach itself would get digested.
