Question

function of parietal cell​

Answer 1

Hydrogen ions are formed from the dissociation of carbonic acid. Water is a very minor source of hydrogen ions in comparison to carbonic acid. Carbonic acid is formed from carbon dioxide and water by carbonic anhydrase.

The bicarbonate ion (HCO3−) is exchanged for a chloride ion (Cl−) on the basal side of the cell and the bicarbonate diffuses into the venous blood, leading to an alkaline tide phenomenon.

Potassium (K+) and chloride (Cl−) ions diffuse into the canalicul

Answer 2

Answer:

Parietal cell are the epithelial cells that secrete hydrochloric acid (HCI) 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
