Answer:
Ingestion is the process of taking in food through the mouth. In vertebrates, the teeth, saliva, and tongue play important roles in mastication (preparing the food into bolus). While the food is being mechanically broken down, the enzymes in saliva begin to chemically process the food as well.
Digestion, sequence by which food is broken down and chemically converted so that it can be absorbed by the cells of an organism and used to maintain vital bodily functions.
In humans and other higher forms of animals, the egestion process entails waves of muscular contractions of the colonic walls, moving the fecal matter towards the rectum. The fecal matter is temporarily stored in the rectum ampulla.
