Quizplus · Accepted Answer

The smell of cookies is a sensory stimulus that triggers the cephalic phase of gastric secretion. During this phase, the brain sends signals to the stomach to prepare for digestion by increasing secretions of digestive juices, including saliva and gastric acid. The mouthwatering sensation is a result of increased saliva production in response to the smell of the cookies. The gastric phase occurs after food enters the stomach, and the intestinal phase occurs after food leaves the stomach and enters the small intestine.
