Pancreatic juice contains several enzymes. The salivary glands begin the digestive process at the sight and smell of food. Where does chemical digestion occur in the tract? Many diseases and disorders related to the digestive system. The colon is rich in the intestinal flora; these bacteria produce some vitamins and other essential chemicals. What is another name for mechanical digestion. Mixed digestion is the name given to the combination of mechanical and chemical digestion that occurs in the stomach and intestines. The remaining waste called feces is gathered in the sigmoid colon until a mass movement called defecation releases the waste through the rectum and anus. The circulating fluids distribute the digested food to all the cells of the body. Salivary glands release saliva during mastication to soften the meal into a bolus (a semi-solid lump). Maltase in the small intestine completes starch digestion by changing maltose to simple sugar. As an enzyme, amylase is a type of protein that undergoes a biochemical reaction to change one molecule into another molecule.
