What would most likely happen if the parietal cells in your stomach stopped functioning?
salantis [7]

If the parietal cells in your stomach stop functioning The pH of the abdomen will rise.

Parietal cells, called oxyntic cells, are stomach epithelial cells that release intrinsic factors and hydrochloric acid (HCl). These cells are present in the stomach's gastric glands, which are situated in the fundus and body regions. Gastric acid secretion, which helps with food digestion, mineral absorption, and bacterial control, is controlled by parietal cells.

In the center of the glands in the fundus-body region of the stomach are the parietal cells. They release the intrinsic factor, a protein that binds vitamin B12, and gastric acid, or hydrochloric acid (about 0.16 M, pH 0.8). The parietal cells that are destroyed are unable to create enough stomach acid. As a result, the pH of the stomach rises, food digestion is hampered, and the risk of gastroenteritis increases.
