Question

Quizplus · Accepted Answer

Cholecystokinin (CCK) is a hormone that regulates digestion and is produced in the small intestine in response to the presence of fats and proteins. Blocking the action of CCK would affect multiple aspects of digestion, including:
A) Acid production by the stomach - CCK stimulates the release of gastric acid from parietal cells in the stomach, so blocking it would reduce acid production.
B) The composition of pancreatic secretions - CCK stimulates the release of enzymes from the pancreas, so blocking it would affect the types and amounts of enzymes released.
C) The delivery of bile - CCK stimulates the contraction of the gallbladder to release bile, so blocking it would reduce the delivery of bile to the small intestine.
