Detailed explanation-1: -Gastrin is primarily released in response to vagal and gastrin-releasing peptide (GRP) stimulation secondary to the ingestion of peptides, amino acids, gastric distention, and an elevated stomach pH.
Detailed explanation-2: -Gastrin release is inhibited by: the presence of acid (primarily the secreted HCl) in the stomach (a case of negative feedback) somatostatin also inhibits the release of gastrin, along with secretin, GIP (gastroinhibitory peptide), VIP (vasoactive intestinal peptide), glucagon and calcitonin.
Detailed explanation-3: -Cholecystokinin is a hormone that functions as part of your digestive system. It’s released (secreted) by your small intestine during the digestive process. It’s sometimes called pancreozymin. Cholecystokinin is also found in your brain and central nervous system, though its function there isn’t as well understood.
