Your circulatory system relies on nearly 100,000 miles of blood vessels to deliver oxygen and nutrients throughout your body. While the blood-flow through your arteries is powered by the pumping of your heart, the veins directing blood back to your heart and lungs rely on a series of one-way valves. These valves defy the pull of gravity to keep your circulatory system functioning efficiently.
In healthy veins, these valves close completely to keep your blood from flowing downward towards your feet. When valves malfunction due to defect or disease, they can eventually cause a significant amount of discomfort and distress. Left untreated, vein disease can lead to a number of chronic health complications, including venous stasis ulcers.
