How it works
The right leg held out to the side, its outer edge at the top. The front view follows the arteries from the aorta to the top of the foot; the back view, from behind the knee to the sole.

Follow the blood down
The aorta splits into the common iliac arteries. On each side the external iliac becomes the femoral artery in the thigh, with the deep femoral beneath it. Behind the knee the femoral becomes the popliteal, which splits into the anterior and posterior tibial arteries. They end on the top of the foot and in the sole.
- Popliteal is behind the knee; it is the femoral artery's name once it passes to the back of the leg.
Questions and answers
What are the main arteries of the leg?
The femoral artery in the thigh, with the deep femoral beneath it; the popliteal artery behind the knee; and the anterior and posterior tibial arteries in the lower leg, with the fibular artery branching from the posterior tibial.
Where can you feel a pulse in the foot?
On the top of the foot, over the dorsalis pedis artery, and behind the inner ankle bone, over the posterior tibial artery.
What is the difference between the femoral and the deep femoral artery?
The femoral artery is the main artery running down the thigh to the knee. The deep femoral artery is its large branch that stays deep and feeds the thigh muscles.
