The parietal cell in the stomach secrets gastric acid, which is hydrochloric acid (HCl). The Secretion of HCl by the parietal cell is stimulated by receptors for acetylcholine (muscarinic), histamine, and gastrin. The enterochromaffin cells (ECL) also have gastrin receptors and muscarinic receptors. ECL cells release histamine which reacts with H2 receptors (histamine 2 receptors) on parietal cells. Somatostatin is released by delta cells and decreases histamine release by ECL cells.

What increases gastric acid secretion?
Gastric acid secretion can be increased by factors such as the presence of food in the stomach, the release of gastrin hormone, histamine stimulation, certain medications like NSAIDs, stress, and smoking.
What is the parasympathetic and Sympathetic effect on the stomach?
The parasympathetic is stimulatory to stomach , increase the gastric secretion and motility while the sympathetic is inhibitory , decrease the gastric secretion and motility

What is the main stimulus for bile secretion from the gallbladder?
Fat in the stomach.

Gastrin is produced in the stomach and starts secretion.
Do fish have stomach acids?
Fish that have a stomach, generally secrete stomach acid (HCl). However, not all fish have a stomach. For example carp have no stomach and thus no stomach acid secretion.
Select the correct statement about the regulation of gastric secretion?
ANSWER IS: Gastric secretion can be stimulated before food has entered the mouth.A.Gastric secretion can be stimulated before food has entered the mouth.B.Gastric secretion is enhanced by very low pH (below a pH of 2)C.The presence of food in the stomach prevents hormonal control of gastric secretion.D.Vagus stimulation of the stomach results in decreased secretion of gastric juice.
What does gastrin stimulate?
Gastrin is a hormone secreted by the stomach which stimulates the secretion of hydrochloric acid, increase motility, and stomach emptying.
