- The Physiology of the Gastric Parietal Cell - PMC
Parietal cells are responsible for gastric acid secretion, which aids in the digestion of food, absorption of minerals, and control of harmful bacteria
- Parietal cell - Wikipedia
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 body regions of the stomach [1]
- Cells of the stomach: Types, purpose, and location
Parietal cells are present in the gastric pits that mainly occur in the upper part of the stomach, or the fundus They secrete hydrochloric acid, which helps break down food
- Stomach Parietal Cell - an overview | ScienceDirect Topics
The parietal cells secrete hydrochloric acid and intrinsic factor, necessary for vitamin B 12 absorption The chief cells contain pepsinogen granules, precursors of the proteolytic digestive enzyme pepsin The endocrine argentaffin cells secrete serotonin and histamine
- The Parietal Cell: Mechanism of Acid Secretion
When stimulated, parietal cells secrete HCl at a concentration of roughly 160 mM (equivalent to a pH of 0 8) The acid is secreted into large cannaliculi, deep invaginations of the plasma membrane which are continuous with the lumen of the stomach
- Parietal cell | Gastric Acid, Hydrochloric Acid Intrinsic . . .
The thick mucous-membrane lining of the walls is densely packed with small gastric gland s; these secrete a mixture of enzymes and hydrochloric acid that partly digest proteins and fats
- Overview of Acid Secretion - Gastroenterology - MSD Manual . . .
Acid is secreted by parietal cells in the proximal two-thirds (corpus or body) of the stomach Gastric acid aids digestion by creating the optimal pH for pepsin and gastric lipase and by stimulating pancreatic bicarbonate secretion
