Answer:
Food is ingested through the mouth and broken down through mastication (chewing). Food must be chewed in order to be swallowed and broken down by digestive enzymes. While food is being chewed, saliva chemically processes the food to aid in swallowing.
Explanation:
The digestive system is composed of the mouth, pharynx, esophagus, stomach, small intestine, large intestine (or colon), rectum, and anus. There are four steps in the digestion process: ingestion, the mechanical and chemical breakdown of food, nutrient absorption, and elimination of indigestible food.
