What prevents food from entering the nasal passages during swallowing? The serosa is... B) outer connective tissue covering of the digestive tract
Definition. gastric secretion. When the pH of the stomach contents is very low, secretion of gastrin by the G cells of the gastric antrum is inhibited. When gastrin secretion is inhibited, further gastric HCl secretion by the parietal cells is also inhibited.
b. Cimetidine is a reversible inhibitor of H2 receptors on parietal cells and blocks H+ secretion. Cyclic adenosine monophosphate (cAMP) levels would be expected to decrease, not increase. Cimetidine also blocks the action of acetylcholine (ACh) to stimulate H+ secretion.
