Question

Quizplus · Accepted Answer

CCK (cholecystokinin) is the hormone that stimulates gallbladder contraction. It is released by cells in the small intestine in response to the presence of fats and proteins in the chyme (partially digested food) entering from the stomach. CCK stimulates the gallbladder to release bile into the small intestine for the digestion of fats. Secretin and gastrin also affect the digestive system, but they do not directly stimulate the gallbladder contraction. Sympathetic stimulation can inhibit gallbladder contraction.
