What is secreted by the chief cells in the stomach?

Chief cells (B or arrow) are located, in cluster, at the base of the glands. They synthesize and secret hydrolytic enzymes, which are activated at acid pH. These enzymes include gastric lipase, rennin and pepsin, which is secreted as pepsinogen and activated in the lumen. Pepsin hydrolyzes proteins.

Just so, what are chief cells in the stomach?

The gastric chief cell (also known as a zymogenic cell or peptic cell) is a cell in the stomach that releases pepsinogen and chymosin. Pepsinogen is activated into the digestive enzyme pepsin when it comes in contact with acid produced by gastric parietal cells.

Where do you find gastric glands?

The three types of gland are all located beneath the gastric pits within the gastric mucosa–the mucous membrane of the stomach. The gastric mucosa is pitted with innumerable gastric pits which house the gastric glands. The fundic glands (or oxyntic glands), are found in the fundus and body of the stomach.

What types of cells are found in the stomach?

Parietal cells (also called oxyntic cells) are the stomach epithelium cells which secrete gastric acid. Parietal cells produce gastric acid (hydrochloric acid) in response to histamine (via H2 receptors), acetylcholine (M3 receptors) and gastrin (gastrin receptors).
