What is the function of the parietal cells?

Parietal cells (also known as oxyntic or delomorphous cells), are the epithelial cells that secrete hydrochloric acid (HCl) and intrinsic factor. These cells are located in the gastric glands found in the lining of the fundus and in the cardia of the stomach.

Herein, what is the function of the chief cell?

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.

What are the secretions of parietal and chief cells?

The two main types of exocrine secretory cells of the stomach are parietal cells and chief cells. Parietal cells secrete hydrochloric acid and chief cells secrete digestive enzymes such as pepsin.

What is the function of G cells?

In anatomy, the G cell (or γ-cell) is a type of cell in the stomach and duodenum that secretes gastrin. It works in conjunction with gastric chief cells and parietal cells. G cells are found deep within the pyloric glands of the stomach antrum, and occasionally in the pancreas and duodenum.
