Document Summary
Absorbed materials enter blood or lymphatic system and there they are distributed to the rest. In passing through the tube materials are prepared and digested and eliminated of the body. Process: food in mouth, thorax, passes epiglottis (flap separates trachea and esophagus and continues down tube of esophagus to abdomen (stomach), to small intestine (where food is digested) then to large intestine (then bladder and out of the body) Amylase - digestive enzyme that starts breaking starch down in mouth. Bolus: name of food/materials travelling through the digestive system. Upper part (pharynx) - we have control over what we are digesting. Smooth muscle beneath the upper part - we no longer have control. Muscularis externa: smooth muscles- outer longitudinal, inner circular, & 3rd layer: stomach- innermost oblique. Serosa tube squeezing lining of mucous epithelium. Gross structure of the small intestine fig. 25-2.
