what is the type of cell in the stomach that secrete hydrochloric acid?
parietal cells
the presence of gastrin stimulates parietal cells of the stomach to secrete hydrochloric acid (hcl)/gastric acid. this is done both directly on the parietal cell and indirectly via binding onto cck2/gastrin receptors on ecl cells in the stomach, which then responds by releasing histamine, which in turn acts in a paracrine manner on parietal cells stimulating them to secrete h+ ions. this is the major stimulus for acid secretion by parietal cells.









































along with the above-mentioned function, gastrin has been shown to have additional functions as well:









































bullet::::- stimulates parietal cell maturation and fundal growth.
gastrin
the fundic glands (or "oxyntic glands"), are found in the fundus and body of the stomach. they are simple almost straight tubes, two or more of which open into a single duct. "oxyntic" means acid-secreting and they secrete hydrochloric acid (hcl) and intrinsic factor.









































the pyloric glands are located in the antrum of the pylorus. they secrete gastrin produced by their g cells.
