What does the femoral artery become beyond the knee?

1. Popliteal artery

2. Femoral vein

3. Saphenous vein

4. Saphenous artery

The correct answer is: Popliteal artery

The femoral artery transitions into the popliteal artery as it passes behind the knee. This change occurs at the adductor hiatus, where the arterial supply continues through the posterior aspect of the leg. The popliteal artery then gives rise to several branches that provide blood flow to the knee and lower leg. Understanding the role of the popliteal artery is crucial, as it serves as a vital conduit for blood flow to the lower leg and foot. The branches of the popliteal artery further divide into anterior and posterior tibial arteries, which are essential for supplying blood to the respective areas of the leg and foot. This highlights the importance of the popliteal artery in the vascular system, particularly as it pertains to the continuation of blood circulation from the femoral artery.
