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.
Your body utilizes two types of digestion: chemical digestion and mechanical digestion. Chemical digestion refers the to the breakdown of food in the mouth, stomach and intestines through the use of acids and enzymes. Mechanical digestion processes--such as chewing, swallowing and the muscular movements that move food through the digestive tract--support chemical digestion by physically breaking whole foods into smaller pieces to facilitate chemical breakdown.
