The cephalic phase of digestion is the first stage of the overall process of digestion. This phase is triggered by the sight, smell, thought, or taste of food, and results in the secretion of saliva in the mouth and gastric juices in the stomach. The main purpose of this phase is to prepare the body for the digestion of food. Here are the steps involved in this phase:

1. Sensory Stimulation: The sight, smell, thought, or taste of food can trigger this phase. This is why sometimes just thinking about food can make your mouth water.

2. Signal to Brain: These sensory stimulations send a signal to the brain, specifically the medulla oblongata.

3. Release of Saliva: The brain then sends a signal to the salivary glands to start producing saliva. Saliva contains enzymes that start the process of breaking down food.

4. Release of Gastric Juices: At the same time, the brain also sends a signal to the stomach to start producing gastric juices. These juices are essential for the digestion of food in the stomach.

5. Ready for Food: With the production of saliva and gastric juices, the body is now ready to start the process of digestion as soon as food enters the mouth.

This is the cephalic phase of digestion. It's a crucial part of the digestive process because it prepares the body for the breakdown and absorption of nutrients.
