Blood is moved throughout the body through veins and arteries. Veins carry the deoxygenated blood back to the heart so it can move through the chambers, go to the lungs and pick up oxygen. Then the arteries take over by pumping the blood back out to the entire body. Veins are bluish in color because of the lack of oxygen. Arteries are the pulse in the body because they must pump the oxygenated blood to the entire body to supply all organs and tissues with oxygen rich blood.

Hope this helps
