Protein digestion happens alot in the stomach

AI Thread Summary
Protein digestion primarily occurs in the stomach, where the secretion of pepsinogen, an inactive enzyme, is crucial. Pepsinogen is activated to pepsin in the acidic environment of the stomach, allowing for protein breakdown. The stomach does not digest itself due to protective mechanisms, including a layer of mucus that lines the stomach walls. This mucus serves as a barrier, preventing the digestive enzymes from damaging the stomach tissue. Additionally, the cells of the stomach are continuously renewed, which further protects against self-digestion.

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
