Stomach – the gastric glands and their secretion

Stomach: Stomach is a reservoir of food particles, where digestion begins. It is the internal organ in which the major part of the digestion of food occurs, being (in humans and many mammals) a pear-shaped enlargement of the alimentary canal linking the esophagus to the small intestine.

The gastric gland is any of the branched tubules in the inner lining of the stomach that secrete gastric juice and protective mucus. The cardiac gastric glands are positioned at the beginning of the stomach. The pyloric glands are found in the terminal stomach region. Both the pyloric and cardiac glands secrete mucus that protects the stomach from self-digestion. The intermediate gastric glands produce the bulk of the digestive substances secreted by the stomach.
