Document Summary
Main function: break down organic nutrients so that they can be absorbed into the body. Organic nutrients can be carbohydrates, proteins, fats, vitamins and minerals. Secretion involves the release of digestive fluids into the lumen of the digestive tract: fluid may include water, mucus, acid, electrolytes, enzymes, bile salts and digestive enzymes. Digestion is the process whereby food is broken down into smaller molecules by the digestive enzymes so they can be taken up by the body. Absorption is the process whereby these small molecules are taken up by the circulatory. Motility is the movement of the (cid:498)food(cid:499) through the digestive system by the contraction of system and are distributed throughout the body smooth muscle that lines the walls of the tract. Excretion is the removal of the unwanted waste products from the body after almost all of the wanted material is absorbed.
