Solution
The cephalic phase of digestion is characterized by the sight, smell or thought of food stimulating the stomach to begin its secretory activity. This phase is essentially a reflex response to the anticipation of eating, preparing the digestive system for the incoming food. The brain sends signals to the stomach, pancreas, and other organs to start producing digestive juices and enzymes. This phase is named "cephalic" because it is controlled by the brain (the head, or "cephalic" region of the body).
