What does the stomach wall releases?

The stomach wall releases gastric juice, which contains hydrochloric acid, pepsinogen, and intrinsic factor. Hydrochloric acid creates an acidic environment that helps break down food and activates pepsinogen into pepsin for protein digestion. Intrinsic factor is essential for the absorption of vitamin B12 in the intestines. Additionally, mucus is secreted to protect the stomach lining from the corrosive effects of acid.
