Question

An empty stomach increases its secretion of ____ to stimulate the appetite.  
A) pepsinogen
B) ghrelin
C) gastric fluid
D) chyme
E) serosa

Accepted Answer

Ghrelin is a hormone that is secreted by the stomach when it is empty. It stimulates the appetite and triggers hunger signals in the brain. Pepsinogen is an inactive form of the enzyme pepsin, which is involved in protein digestion. Gastric fluid is the combination of acid and enzymes that are secreted by the stomach to digest food. Chyme is the partially digested food that leaves the stomach and enters the small intestine. Serosa is the outermost layer of the stomach that provides a protective barrier.
