Quizplus · Accepted Answer

CCK (cholecystokinin) is a hormone released by the small intestine in response to the presence of fatty acids and partially digested proteins. It stimulates the contraction of the gallbladder, which releases stored bile into the small intestine to aid in digestion and absorption of fats. Secretin, while involved in digestive processes, does not directly stimulate gallbladder contraction. Sympathetic stimulation actually inhibits gallbladder contraction, rather than stimulating it.
