Protein digestion happens alot in the stomach

Okay so protein digestion happens a lot in the stomach...how come the stomach doesn't just digest itself??

SAme with in the cell walls the stomach produces pepioinogen...so what does protien digestion do in that area.
and how come the cells don't digest themselves

The stomach is protected by excreted proteins that line the stomach, I'd have to look up the details.

yea that's the mucus...it protects the enzymes digesting the walls of the stomach
