The reduction through mechanical and chemical means (hydrolysis) of complex food substances into simple monomers and their absorption into the internal environment.. Understanding:. The contraction of circular and longitudinal muscle layers of the small intestine mixes the food with enzymes and moves it along the gut. The pancreas secretes enzymes into the lumen of the small intestine. TEMPORALMANDIBULAR DYSFUNCTION. TRIGEMINAL NERVE. sAliva. AND GOOBERS. U SECRETE 36 FL. OZ. OF GOOBER PER DAY.

Alimentary canal . – long muscular tube that runs from the mouth to the . anus. . Peristalsis . – muscular movement of food. BIOMEDICAL IMPORTANCE. Besides water, the diet must provide metabolic fuels (mainly carbohydrates and lipids), protein (for growth and turnover of tissue proteins), fiber (for roughage), minerals (elements with specific metabolic functions), and vitamins and essential fatty acids (organic compounds needed in small amounts for essential metabolic and physiologic functions). . The digestive processes gradually break down the foods eaten until they are in a form suitable for absorption.. For example, meat, even when cooked, is chemically too complex to be absorbed from the alimentary canal.. 267 The digested end products are absorbed into the body through the epithelial liningof the intestinal villi.
