Legs and veins

Our legs do amazing things: day in, day out, they carry us through life. The leg veins play an important role in this task: they transport the blood back to the heart, and must therefore work against gravity. In this, they are supported by the venous values which act like valves and thus prevent the blood from sinking down into the legs. As long as the venous walls maintain their resilience and the venous valves remain elastic, we feel comfortable on our legs.
