THORAX ABDOMEN AND PELVIS

Detailed explanation-1: -Pepsin is a stomach enzyme that serves to digest proteins found in ingested food. Gastric chief cells secrete pepsin as an inactive zymogen called pepsinogen.

Detailed explanation-2: -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 hydrochloric acid produced by gastric parietal cells.

Detailed explanation-3: -Chief cells are the other type of exocrine secretory cells in the stomach. They secrete digestive enzymes that cleave the proteins in meals into smaller pieces. Pepsin is secreted as an inactive enzyme known as pepsinogen that is secreted via way of means of the chief cell.

Detailed explanation-4: -In mammals, chief cells are located at the base of glands distributed throughout the fundus and corpus of the stomach. It is thought that chief cells derive from mucous neck cells located in the midportion of the glands.
