Parietal cells (also called oxyntic cells) are the stomach epithelium cells which secrete gastric acid. HCL also triggers the release of enzymes such as pepsin which are essential for the digestion of protein. They contain an extensive secretory network of canaliculi from which the HCl is secreted by active transport into the stomach. Parietal cells (also known as oxyntic cells) are epithelial cells in the stomach that secrete hydrochloric acid (HCl) and intrinsic factor.These cells are located in the gastric glands found in the lining of the fundus and cardia regions of the stomach. Similar to the mouth, the stomach empties the sugar into your intestines before it has a sufficient amount of time to fully break the sugar into monosaccharides. It is known that the capacity of the stomach to secrete HCl is almost linearly related to parietal cell numbers. Gastric glands: The parietal cells of the gastric glands secrete HCl and hydrolyzes sucrose to some extent. Its role is to create an acidic medium in the stomach so that other enzymes and gastric juices could do their work well. Your stomach lining contains specialized cells, called parietal cells, that release stomach acid in the presence of food. The three main roles of the stomach are to store the food prior to being digested, to secrete enzymes and hydrochloric acid so the food is more digestible, and to keep the food from dumping into the small intestines all at once.
