Epithelial cells lining the inside stomach secrete a substance which prevents the stomach acid harming the lining of the stomach.
Mucus produced by goblet cells in the lining the stomach forms a protective layer preventing the stomach from digesting itself.
The cell that might be used to help the stomach digest is called trypsin. Also is do to protection by the stomach mucosa that is resistant to the stomach digesting itself. The stomach is lined with dense layers of epithelial cells.
The role that cells play in keeping the stomach from digesting itself is in the production of a thick, greasy mucus so that the stomach wall remains intact. This thick mucus is called glycoprotein.
The stomach is protected by the epithelial cells, which produce and secrete a bicarbonate-rich solution that coats the mucosa. Bicarbonate is alkaline, a base, and neutralizes the acid secreted by the parietal cells, producing water in the process. This continuous supply of bicarbonate is the main way that your stomach protects itself from autodigestion (the stomach digesting itself) and the overall acidic environment.
No the stomach most definitely is not an enzyme. Enzymes are molecules which catalyse reactions in the body. The stomach is an organ, although it does produce certain enzymes, it isn't one itself.
Yes, absolutely.The stomach secretes digestive juices that are mostly involved in digesting proteins. This is a chemical digestion process that mostly involves hydrochloric acid and pepsinogen, secreted by the parietal cells and chief cells.
Lysosomes main function is to kill bacteria. Stomach cells line the interior of your stomach so the lysosomes are needed to kill any bacteria or foreign substance that attaches itself to your stomach. The same idea applies to your intestine.
gastric pits contain 3 main types of cells, the mucousa cell which produces mucus that lines the inside of the stomach to stop the stomach acid from digesting itself. the pariental which secretes hydrochloric acidby active transport into the stomach to aide breaking down the foods. and the chief cell which secretes pepsin, an emzyme that breaks down food intomore soluble pieces which can be then taken into the intestines to be absorbed.

Granted pepsin could kill a cell by hydrolyzing crucial proteins, it doesn't specifically destroy cells. It is a protease, a protein-digesting enzyme. There are two reasons why pepsin does not, under normal conditions, turn around and start digesting the cells of the host. Pepsin is only present in the stomach, where it is compartmentalized from the rest of the body. The mucous membrane protects the lining of the stomach so the stomach is not degraded by the enzymes or the strong hydrochloric acid. Secondly, pepsin is only active as an enzyme in very acidic environments like that of the stomach. Once the chyme of the stomach is dumped into the duodenum of the small intestine, the pH increases dramatically and the pepsin is denatured, no longer active to digest protein.
Because your stomach is well lined with mucus producing cells that line the stomach with mucus that keep HCl from digesting the stomach it has been secreted into. When you vomit the mucus come up with the acid to protect, to a degree, you esophagus and mouth. Hydrochloric acid ingested would burn tour mouth and esophagus on the way to your stomach.
