What is "popliteal vein"?

The popliteal vein is a single large vein found behind the knee in the human body. It is responsible for collecting deoxygenated blood from the smaller veins in the lower leg and thigh and returning it to the heart for oxygenation. As one of the main pathways for venous blood flow in the leg, the popliteal vein plays a vital role in maintaining proper circulation and facilitating efficient drainage from the lower extremities.
