Greetings, so today we're going to finish up some of our discussion of how we make acid. And this is going to be the regulation of acid secretion by the stomach.

The glands of the stomach secrete a strong acid, hydrochloric acid (HCl), and protein-digesting enzymes. The stomach acid also serves to kill bacteria entering the organ. The gastric mucosa is vulnerable to damage, but is protected by high turnover, tight junctions, mucus, and bicarbonate (HCO3-) secretions.

Hence, gastric H +, K +-ATPase are prominent target for drugs that treat excess stomach acid secretion. The main research question in this area of study is how such a highly acidic environment can be.

This is as the food is leaving the stomach, then the pH is, falling back to basal levels, which is a pH of two. Secondly, the gastric acid secretion by the parietal cell is stimulated by parasympathetic activity. This is just the smell of food, thinking of food, seeing food, that will activate the proton pump.

Stomach acid test. Stomach fluid is removed through a tube that is inserted into the stomach through the esophagus (food pipe). A hormone called gastrin may be injected into your body. This is done to test the ability of the cells in the stomach to release acid. The stomach contents are then removed and analyzed.
