Before we eat the food our mind start the work for the food Digestion and make ground for that. Then our mouth and stomach do our work and digestion end by ending the work of our intestines
  1. Cephalic Phase:

     In the cephalic phase of digestion, the anticipation of food prepares the body for the digestion, absorption and use of energy in food.The feel of food in the mouth or thoughts related  to food send signals to the medulla oblongata via the vagus nerve to stimulate the release of stomach chemicals. Vagus nerve is the longest nerve originating in the brain, and extends through the abdomen.
  2. Gastric Phase:

    The Gastric phase starts our stomach when food entered in the stomach by releasing the gastric juices. Which play a very vital role in digestion. This process helps to intake food and digestion.
  3. Intestinal Phase: 

    The intestinal phase starts when food reach in duodenum (small intestine).
