Quizplus · Accepted Answer

GI tract hormones are secreted by various organs in the digestive system and they affect the functions of those same organs by regulating their secretion and motility. For example, the hormone gastrin is produced by the stomach and stimulates acid secretion, while cholecystokinin (CCK) is produced by the small intestine and stimulates pancreatic enzyme release and gallbladder contraction.
