Question

Which of the following are functions of the gallbladder?
A) secretion of cholecystokinin
B) secretion of gastrin
C) storage and modification of bile
D) breakdown of erythrocytes
E) storage of lymph

Accepted Answer

The gallbladder's main function is to store and concentrate bile that is produced by the liver. It also has the ability to modify the composition of the bile by absorbing water and ions, which helps to keep the bile in a concentrated form. Therefore, it plays an important role in the digestion and absorption of fats in the small intestine.

Answer: A 
 While the gallbladder does not produce cholecystokinin (CCK), it does play a role in responding to this hormone. When the small intestine detects the presence of fatty acids and amino acids, it releases CCK, which triggers the gallbladder to contract and release bile into the small intestine to aid in the digestion of fats.
