The heart pumps blood through a system of blood vessels called the circulatory system. Blood vessels are of three types: arteries, capillaries, and veins. These blood vessels carry blood to and from the heart. The heart continuously pumps blood, which flows throughout the body via blood vessels...
In the diagram above, the blood vessels of the circulatory system are colored according to whether they carry blood that is high in oxygen (red) or low in oxygen (blue). Most arteries, which carry blood away from the heart, are colored red; most veins, which carry blood back toward the...
