Explanation:
Detailed explanation-1: -BBS/GRP stimulates the release of almost all GI hormones, intestinal and pancreatic secretions, and motility [157]. Although the most important functions of BBS/GRP are to regulate antral gastrin release and gastric acid secretion, this peptide also stimulates growth of the GI mucosa and pancreas.
Detailed explanation-2: -The entry of partially digested acidic chyme into the duodenum stimulates specialized mucosal cells to release two important polypeptide hormones into blood; secretin (from duodenal S cells), and cholecystokinin (CCK, from duodenal I cells).
Detailed explanation-3: -Gastrin is a hormone produced by the stomach, which stimulates gastric motility and the release of gastric acid.
