Answer:
earliest phase of digestion in which the brain prepares the body in anticipation of food
Explanation:
The cephalic phase is the phase that occurs in the process of gastric secretion. The phase witnesses its initiation when the thought, smell, taste and sight of the food lingers in the mind before its consumption. The nerves sends the signals of the food from the cerebral cortex of the brain. Before the food is consumed or entered in the body, the cephalic phase takes place.
