There are three major types of blood vessels: the arteries, which carry the blood away from the heart; the capillaries, which enable the actual exchange of water and chemicals between the blood and the tissues; and the veins, which carry blood from the capillaries back toward the heart.
Arteries carry oxygenated blood away from the heart to the tissues, except for pulmonary arteries, which carry blood to the lungs for oxygenation. (Usually veins carry deoxygenated blood to the heart but the pulmonary veins carry oxygenated blood.) There are two unique arteries.The pulmonary artery carries blood from the heart to the lungs, where it receives oxygen.rteries carry oxygenated blood away from the heart to the tissues, except for pulmonary arteries, which carry blood to the lungs for oxygenation.
