Question

state the mechanism of human digestive process

Answer 1

Digestion. ... In chemical digestion, enzymes break down food into the small molecules the body can use. In the human digestive system, food enters the mouth and mechanical digestion of the food starts by the action of mastication (chewing), a form of mechanical digestion, and the wetting contact of saliva.

There are four stages to food processing for humans. Ingestion is the first stage, where food is taken into the body by mouth. Next, digestion is the physical and biochemical breakdown of food.
