The circulatory system consists of your heart, blood and blood vessels. There are three types of blood vessels: arteries, veins and capillaries. Nutrients are transported throughout your body through your blood via capillaries, tiny blood vessels that connect arteries to veins. Nutrients, oxygen and wastes all pass in and out of your blood through the capillary walls.
Circulatory system consists of Blood and blood vessels. The Nutrients are taken in the blood stream through the single celled wall of capillaries that surround the Intestines and gasses through the wall of capillaries that surround the alveoli. Theses essential nutrients then diffuse into the cell and cell wastes are diffused out of the cell into the blood stream.
