 Dear students, in this topic we shall discuss the transport of absorbed nutrients in the body. The absorbed products of digestion enter from the villi into either blood circulation or into the lymphatic system, because villi have both types of these vessels, blood vessels as well as lymphatic vessels, so these substances either enter in blood circulation or in the lectaels of the villi. The sugars and amino acids enter the blood capillaries of the villi. These capillaries drain then into the venules. These venules combine to form the hepatic portal vein which takes these substances from the intestine to the liver. In the liver, the cells of the liver take up much of the glucose or under the influence of insulin, these hepatocytes convert these glucose into glycogen and store it in the form of this glycogen. Only a controlled quantity of glucose is released in the blood for circulation and delivery to the cells and tissues. The fat in the vertebrates is about 80% fat, in the form of chylomicrons, the lectaels of the villi enter and then the lymphatic vessels carry them into the body. However, only 20% products of digestion of fats enter in the blood circulatory capillaries and directly circulate through the blood. The chylomicrons that enter in the lymphatic system are finally poured into the bloodstream because lymph empties itself in the thoracic lymphatic vessel and in this way these fats are delivered in the blood for further circulation.
