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.
Both mechanical digestion and chemical digestion are necessary for the digestion of foods and beverages into pieces and molecules that are small enough to be absorbed in the small intestine. Both types of digestion are important and complement each other in the digestive process. There are, however, significant differences in the two types of digestion. Mechanical digestion involves the process of physically breaking down the food into ever smaller parts. The major player in mechanical digestion is mastication, which is the act of chewing and using the teeth to break the food into pieces small enough to be swallowed into the esophagus.
