How Do Veins Work?


It's no secret that varicose veins and other venous conditions can have a profound effect on your daily life. However, many patients suffer for years without realizing they have a problem. Understanding how veins work can help you determine if and when to seek treatment from a vein specialist like Dr. Cooper.


Vein Anatomy

Veins carry blood to and from different parts of the body. While arteries transport oxygen-rich blood from the heart to other regions, the primary function of veins is to transport this blood back to the heart again.

The human leg contains 3 types of veins: superficial, deep, and perforating. Responsible for transporting blood to the perforating veins, superficial veins run vertically just under the skin's surface. As a result, this type of vein is generally visible to the naked eye.

On the other hand, deep veins are located deep in the leg muscle and run parallel to the superficial veins. These essential veins transport 90% of the blood in your legs back to your heart.

Finally, perforating veins connect the superficial and deep veins. However, veins only work correctly if valves close all the way.

In a properly functioning vein, blood is squeezed out when the muscles in your calf contract. When the muscles relax, the valves in the veins temporarily close to prevent blood from flowing away from the heart. If the vein doesn't close all the way, blood may start to backflow.
