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.
Chemical digestion differs from mechanical digestion, which occurs in the mouth as the teeth grind and chew pieces of food. Some mechanical digestion also takes place in the stomach as the muscles churn food particles.hemical digestion breaks down carbohydrates, proteins and fats into sugars, amino acids and fatty acids that the body can absorb and use as fuel.
