Which digestive secretion is correctly matched to its function?

C)cholecystokinin (CCK)- release of alkaline pancreatic juices and bile
D)GIP - decreased release of bile

Question

Quizplus · Accepted Answer

Cholecystokinin (CCK) is correctly matched to its function of releasing alkaline pancreatic juices and bile. It is secreted by the small intestine in response to the presence of fat and protein in the duodenum, and acts on the pancreas and gallbladder to stimulate the release of digestive enzymes and bile, respectively. Gastrin stimulates the release of gastric acid, not alkaline secretions from the pancreas. Secretin stimulates the release of bicarbonate ions, not hydrochloric acid. GIP, or gastric inhibitory peptide, reduces gastric acid secretion and stimulates insulin release, but it has no direct effect on bile secretion.
