Locations of mechanical and chemical digestion. Mechanical digestion occurs in the mouth and stomach, Segmentation is the back and fourth mixing of food in stomach.Chemical digestion occurs in the stomach were Hcl and pepsin forms chyme, the mouth in which salivary amylase breaks down starch to form bolus, and the small intestine specifically the duodenum.he liver makes bile, the gall bladder stores it, and the pancreas makes digestive enzymes like lactase, lipase, proteases, amylase, and most important insulin.
Digestion is a form of catabolism that is often divided into two processes based on how food is broken down: mechanical and chemical digestion. The term mechanical digestion refers to the physical breakdown of large pieces of food into smaller pieces which can subsequently be accessed by digestive enzymes. 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.
