Which cells in the stomach secrete hydrochloric acid?
Parietal cells within the stomach lining secrete hydrochloric acid that lowers the pH of the stomach. A low pH (1.5 to 2) activates pepsin. Acetylcholine, gastrin, and histamine stimulate the proton pump in parietal cells to release hydrogen ions and decrease pH.
Which cells of the stomach secrete hydrochloric acid and the intrinsic factor quizlet?
Parietal cells (also known as oxyntic or delomorphous cells), are the epithelial cells that secrete hydrochloric acid (HCl) and intrinsic factor. These cells are located in the gastric glands found in the lining of the fundus and in the body of the stomach. You just studied 10 terms!
What does the stomach secrete quizlet?
Pepsin, which is secreted as pepsinogen by chief cells of the stomach, initiates the degradation of proteins to peptides in the stomach.
What cells produce hydrochloric acid HCl?
In the human body, HCl is produced by the parietal cells of the stomach lining. The parietal cell cytoplasm combines with water and carbon dioxide to produce carbonic acid. The enzyme carbonic anhydrase converts one carbonic acid ion into a single hydrogen ion (H+) and a single bicarbonate ion (HCO3u2013).
