Parietal cells secrete

Histamine, is the major stimulant for acid secretion. Stimulation triggers dramatic morphological changes in the parietal cell from the resting state to the stimulating state. Parietal cells contain an extensive secretory network (called canaliculi) from which the HCl is secreted by active transport into the stomach. The enzyme hydrogen potassium ATPase (H + /K + ATPase) is unique to the parietal cells and transports the H + against a concentration gradient of about 3 million to 1. When parietal cells are stimulated they secrete? When stimulated , parietal cells secrete HCl at a concentration of roughly 160 mM (equivalent to a pH of 0.8).

Hydrochloric acid is secreted by the parietal cells of the gastric glands, located on the wall of the fundus of the stomach. This book consists of 25 chapters that evaluate the diseases of the buccal mucous membranes, the control of acid secretion by parietal cells, and the causes of operate can be made. Acid secretion after RYGBP.

hydrochloric acid c. pepsin d. pepsinogen The parietal cells secrete hydrochloric acid–the main component of gastric acid. This needs to be readily available for the stomach in a plentiful supply, and so from their positions in the walls, their secretory networks of fine channels called canaliculi can project and ingress into all the regions of the gastric-pit lumen.

These cells have histamine type 2, and muscarinic cholinergic receptors in the basolateral membranes. Histamine, is the major stimulant for acid secretion. Stimulation triggers dramatic morphological changes in the parietal cell from the resting state to the stimulating state. parietal cells secrete.

When acid secretion is stimulated there is a dramatic change in the morphology of the membranes of the parietal cell.
