Question

Quizplus · Accepted Answer

Gallbladder contraction is stimulated by the hormone cholecystokinin (CCK), which is released by the small intestine in response to the presence of fat and protein in the duodenum. CCK causes the gallbladder to contract, releasing bile into the common bile duct and ultimately into the small intestine to aid in the digestion and absorption of fats. Secretin and gastrin do not directly stimulate gallbladder contraction, and sympathetic nerve impulses and epinephrine can inhibit rather than stimulate gallbladder contraction.
