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.
Mechanical digestion involves physically breaking the food into smaller pieces. Mechanical digestion begins in the mouth as the food is chewed. Chemical digestion involves breaking down the food into simpler nutrients that can be used by the cells.Chemical digestion begins in the mouth when food mixes with saliva.Saliva contains an enzyme (amylase) that begins the breakdown of carbohydrates.he organs produce digestive chemicals (enzymes and acids) that break down the nutrients into simpler forms so that absorption through the intestinal wall and into the blood stream can occur.
