Examples of gastrointestinal hormones

Here are some examples of gastrointestinal hormones:

• Gastrin: Produced by the stomach, it stimulates the secretion of gastric acid and pepsinogen.

• Secretin: Released by the small intestine in response to acidic chyme, it stimulates the pancreas to release bicarbonate-rich fluid to neutralize the acid.

• Cholecystokinin (CCK): Secreted by the small intestine, it stimulates the gallbladder to release bile and the pancreas to release digestive enzymes. It also promotes satiety.

• Ghrelin: Primarily produced by the stomach, it stimulates appetite and food intake.

• Motilin: Released by the small intestine, it stimulates gastrointestinal motility, particularly during fasting periods.
