Question

Quizplus · Accepted Answer

Cholecystokinin does not affect the absorption of water in the large intestines, therefore blocking its action would not have an effect on this process. However, cholecystokinin does stimulate the relaxation of the hepatopancreatic sphincter, the secretion of pancreatic enzymes and bicarbonate, and the contraction of the gallbladder to release bile, as well as promoting the digestion of lipids and proteins.
