Which artery is the major supplier of blood to the leg?

The femoral artery is the primary vessel that supplies blood to the leg, making it the correct answer. It originates from the external iliac artery and travels down through the thigh, where it branches into various arteries that serve the different regions of the leg. As it approaches the knee, it transitions into the popliteal artery, which further supplies the lower leg and foot.

Understanding the anatomy and blood supply is crucial, as the femoral artery is not only significant for its size but also for its role in delivering oxygenated blood to the leg's muscles and tissues. Other arteries mentioned may supply specific regions of the leg, but none can be credited with the same level of overall contribution to the lower limb as the femoral artery. The popliteal artery serves specific distal areas after the femoral artery, the dorsalis pedis artery primarily supplies the foot, and the peroneal artery branches off from the posterior tibial artery to supply the lateral aspect of the leg. Each has its importance in vascular anatomy, but the femoral artery is key in the overall blood supply to the leg.
