The blood vessels are responsible for transporting blood throughout the body. There are three major types of blood vessels: arteries, veins, and capillaries. Oxygen is the most important nutrient carried by the blood. Arteries carry oxygenated blood from the heart to all the structures of the body. Capillaries are very small, permeable vessels at which the exchange of water and chemicals between the blood and body tissues takes place.
