Blood flows through a system of blood vessels, which are veins and
arteries. Arteries carry blood rich in oxygen from your heart to all
regions of the body. The function of veins is to transport the blood
back to the heart. In order for veins to work, the valves must close all
the way to prevent backflow of blood. When the muscles in your calf
contract; blood is squeezed from the veins. When the muscles in your
calf relax, the valves in the veins temporarily close to prevent the
blood from flowing away from the heart, in the wrong direction!
In your legs, there are 3 types of veins; superficial, perforating, and
deep veins. Think of the perforating veins as connecting the superficial
veins to the deep veins. If you are standing, superficial veins run
vertically, just beneath the surface of the skin and are often times
visible to the naked eye. Superficial veins are responsible for
transporting as little as 10% of the blood in the legs. The 10% of blood
carried in the superficial veins flow directly into the perforating
veins. The perforating veins run perpendicular to superficial veins and
again, their function is to connect the superficial veins to the deep
veins. Deep veins are located deep within the muscle of your leg and run
parallel to superficial veins. Deep veins are responsible for
transporting as much as 90% of the blood in your legs back to your
heart.
