8 Questions
Match the gut hormone with its primary function:
Gastrin = Stimulates the release of gastrin, hydrochloric acid, secretin, cholecystokinin, and glucagon Somatostatin = Stimulates the stomach to secrete gastric juice (hydrochloric acid and pepsin) Secretin = Inhibits the release of gastrin, hydrochloric acid, secretin, cholecystokinin, and glucagon Cholecystokinin (CCK) = Stimulates the pancreas to secrete bicarbonate
Match the gut hormone with its primary function:
Fibroblast growth factor 19 (FGF19) = Enhance glucose-stimulated insulin secretion, increase glucose uptake by tissues Incretins (GLP-1 and GIP-1) = Stimulates glucose uptake and conversion to glycogen in the liver, synthesis of bile acids Ghrelin = Inhibits feeding, released by intestinal cells in response to feeding (especially protein-rich meals) Neuropeptide Y (NPY) = Stimulates bile secretion into the intestines, releases pancreatic digestive enzymes, and induces satiety
Match the gut hormone with its primary function:
Peptide YY3-36 (PYY) = Stimulates the stomach to secrete gastric juice (hydrochloric acid and pepsin) Ghrelin = Secreted by the stomach when hungry; stimulates feeding by acting on the hypothalamus Neuropeptide Y (NPY) = Inhibits feeding, released by intestinal cells in response to feeding (especially protein-rich meals) Secretin = Stimulates the pancreas to secrete bicarbonate, which neutralizes intestinal contents and protects mucous membranes

Study Notes
Gastrin
- Stimulates the stomach to secrete gastric juice, which consists of hydrochloric acid and pepsin.
Somatostatin
- Inhibits the release of gastrin, hydrochloric acid, secretin, cholecystokinin, and glucagon.
- Reduces the rate of digestion and nutrient absorption.
Secretin
- Stimulates the pancreas to secrete bicarbonate.
- Neutralizes intestinal contents and protects mucous membranes from stomach acid.
Cholecystokinin (CCK)
- Stimulates bile secretion into the intestines.
- Releases pancreatic digestive enzymes.
- Induces satiety by stimulating the vagus nerve.
Fibroblast Growth Factor 19 (FGF19)
- Stimulates glucose uptake and conversion to glycogen in the liver.
- Stimulates the synthesis of bile acids.
- Causes the gall bladder to relax and collect bile.
Incretins (GLP-1 and GIP-1)
- Enhance glucose-stimulated insulin secretion.
- Increase glucose uptake by tissues.
- Slow stomach emptying.
- Suppress glucagon secretion.
- Reduce appetite and food intake.
Ghrelin
- Secreted by the stomach when hungry.
- Stimulates feeding by acting on the hypothalamus.
Neuropeptide Y (NPY)
- Secreted by neurons in the hypothalamus.
- Potent stimulator of feeding.
Peptide YY3-36 (PYY)
- Inhibits feeding.
- Released by intestinal cells in response to feeding, especially protein-rich meals.
- Acts on the hypothalamus to suppress appetite.
- Stimulates bile release and pancreatic exocrine secretion.
Test your knowledge on the functions of gut hormones such as Gastrin, Somatostatin, Secretin, and Cholecystokinin. Learn how these hormones regulate digestion and nutrient absorption in the gastrointestinal system.
