In the stomach there are gastric pits. An individual pit contains surface mucous cells and mucous neck cells, which secrete a coat of mucus and bicarbonate throughout the stomach. The Parietal cells (aka oxyntic cells), which are deeper within the pit, also produce bicarbonate.(parietal cells are also the ones who produce HCl) The bicarbonate is secreted into the blood stream and as the blood vessels carry the bicarbonate away some of it diffuses from the blood vessel into the mucus coat. This mucous coat containing bicarbonate is thus able to protect the inside of the stomach from the HCl. It's just like a lining in the stomach which is replaced every so often More simply put, cells in the stomach secrete mucus and a base, bicarbonate. This mucus coat containing the base is able to neutralize the acid secreted by another group of cells. The stomach contents is acidic, but the acid is neutralized by the mucus if the acid trys to come in contact with the cells of the stomach. violingal is the author=-] add her if read.

The inner epithelium of the stomach is covered by sugars (mucus) which help protect from self-degradation. What's more the body regulates the amount of acid in the stomach, meaning that acidic secretion is "turned off" when there's no food to digest inside of it.

The stomach produces a thick layer of mucus to prevent the acid from dissolving the stomach lining. When the mucus is too thin or the acid to strong stomach ulcers may develop where the acid has burned the stomach lining.

Both the stomach and the intestines are designed to digest food which is very similar in composition to the stomach and intestine. The acids (in the stomach), alkalis (in the intestine) and various digestive enzymes are prevented from doing this by mucous excreted by the surfaces in both sites. The action of moving food scrapes this muous away but it is replenished as quickly as it is removed by special cells so the coverage is continuous.
