The villiprovide a large surface area with an extensive network of capillaries to . This makes sure that none of the digested food is wasted and lost as faeces. So in order to obtain these molecules from our diet, the large protein must be digested (broken down) into the smaller amino acid subunits. Eating a high-protein meal increases the amount of time required to sufficiently break down the meal in the stomach. Once in the blood, the food molecules are routed to every cell in the animal's body. Digestive proteases are synthesized as larger, inactive forms (zymogens), which, after secretion, are cleaved to produce active proteases. Hence, they are first incorporated into small droplets called micelles and then transported into the villi of the intestinal mucosa. Through the action of a group of potent enzymes from the intestinal lining and the pancreas, digestion continues in the small intestine. Blood vessels in the Wall of large intestine absorbs the extra water. The digestible carbohydrates are broken into simpler molecules by enzymes in the saliva, in juice produced by the pancreas, and in the lining of the small intestine. This makes the villi well adapted to absorb the products of digestion by diffusion and active transport. Adrenaline relaxes the muscle of the stomach and intestine and decreases the flow of blood to these organs. This means that they pass through the wall of the small intestine and into our bloodstream. Milk contains yet another type of sugar, lactose, which is changed into absorbable molecules by an enzyme called lactase, also found in the intestinal lining. The nutrient passes out of the body as waste. The major hormones that control the functions of the digestive system are produced and released by cells in the mucosa of the stomach and small intestine. chemical digestion: The process of enzymes breaking down food into small molecules the body can use. . Acetylcholine also causes the stomach and pancreas to produce more digestive juice. The bile acids combine with the fatty acids and cholesterol and help these molecules to move into the cells of the mucosa.
