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.
Chemical digestion that occurs in the stomach is mainly via enzymes and hydrochloric acid. The stomach secretes pepsinogen which turns into pepsin and breaks down proteins.The hydrochloric acid provides a low pH level in which the enzymes can thrive.hemical digestion is the breaking down of food particles through chemical reactions. Chemical and mechanical digestion combine to process food, absorbing nutrients and minerals and discarding the waste. Very little mechanical digestion occurs outside of the mouth.
