Quizplus · Accepted Answer

Secretin is released during the intestinal phase of gastric secretion, not during the cephalic phase. The cephalic phase is initiated by the thought, smell, sight, or taste of food which triggers the vagus nerve to stimulate the gastric glands. This results in the release of gastric juices such as hydrochloric acid and pepsinogen that help in digestion.
