The hormone gastrin
Correct answer: B. stimulates the gastric glands to secrete more gastric juice
- A. stops the stomach from emptying
- B. stimulates the gastric glands to secrete more gastric juice
- C. is secreted by the pancreas
- D. digests protein in the stomach
Explanation
Gastrin is released into the blood by cells in the stomach lining when food arrives and returns to the same organ to increase the output of acid and pepsinogen, an example of hormonal rather than nervous control of digestion. Secretin and cholecystokinin work later, from the duodenum, to call for pancreatic juice and bile. A hormone is a chemical messenger, so gastrin does no digesting itself.

About Human Digestive System
The human digestive system breaks food into absorbable molecules through mechanical processing, enzyme action and chemical conditions along the alimentary canal. Questions cover the mouth, stomach, small and large intestines, liver, pancreas and associated secretions, including the digestion and absorption of carbohydrates, proteins, lipids, vitamins, minerals and water.
