Answer :
Cholecystokinin, secretin, and the vagus nerve all stimulate the release of pancreatic juices. Secretin causes the secretion of bicarbonate, CCK the release of digestive enzymes, and the vagus nerve enhances the secretion through parasympathetic stimulation.Thus, the correct answer is option B.
Cholecystokinin, secretin, and the vagus nerve all stimulate the release of pancreatic juices. Secretin primarily stimulates the pancreas to secrete bicarbonate, which neutralizes the acidic chyme in the duodenum. Cholecystokinin (CCK) promotes the release of digestive enzymes from the pancreas. Additionally, the vagus nerve plays a role in this process through parasympathetic stimulation, promoting the secretion of pancreatic juices during the cephalic and gastric phases of gastric secretion.Thus, the correct answer is option B.
