It protects the stomach wall from acid
gastric juice is made of · A protease called pepsin. · Dilute HCl which activates the pepsin and provides the correct pH for it to work. Also kills bacteria. · Mucus - which protects the wall of the stomach from self digestion and acid damage. = Gastic Acid.

The gastric juice needs to be acid so that it can break down the food to go to the intestine. The muscles of the stomach wall contract vigorously so that the food is mixed with the gastric juice. Pepsinogen is made by the presence of gastric juice. This digests protein. Seeing, smelling, tasting or thinking about food starts the production of gastric juice.
A perforating gastric ulcer can lead to damage to the pancreas if it erodes through the wall of the stomach and affects nearby structures like the pancreas. This can cause inflammation in the pancreas and lead to complications such as pancreatitis. The close proximity of the stomach and pancreas allows for potential spread of infection or inflammation from a perforated ulcer to the pancreas.

Gastric fluid is composed primarily of hydrochloric acid, along with enzymes like pepsin for protein digestion, mucus for protection of the stomach lining, and intrinsic factor for vitamin B12 absorption. It also contains electrolytes such as sodium, potassium, and chloride.
Gastric glands in frogs are structures located in the stomach lining that secrete digestive enzymes and hydrochloric acid to help break down food. These glands play a crucial role in the digestion process of frogs by aiding in the breakdown of food into nutrients that can be absorbed by the body.
The general term is a stomach ulcer.
You have the glands in the wall of stomach. You have the cells that secrete the mucus. You have the chief cells that secrete the precursor of the enzyme pepsin. This precursor is called as pepsinogen. Then you have the parietal cells that produce the hydrochloric acid. You have the hormones that induce the production of the gastric juice, when food enters the stomach. The same is controlled through the autonomic nervous system also. Like when you see or smell the food.
