The Gallbladder

Question

The gallbladder
A) contracts in response to cholecystokinin.
B) synthesizes bile.
C) concentrates and stores lipases.
D) does all of the above.

Accepted Answer

The gallbladder contracts in response to cholecystokinin, a hormone released by the duodenum in response to the presence of fatty acids and amino acids. This contraction releases stored bile into the small intestine, aiding in the digestion and absorption of dietary fats. The gallbladder does not synthesize bile or store lipases.
