What is the arterial supply to lower limb?

The bony pelvis and lower limbs receive vascular supply from the distal continuations of right and left common iliac arteries. The primary blood supply to the bony pelvis is from the divisions of iliac arteries while the lower limbs receive supply via obturator artery and divisions of the common femoral artery.

Which artery branches in the lower limbs?

The arterial supply of the lower limbs originates from the external iliac artery. The common femoral artery is the direct continuation of the external iliac artery, beginning at the level of the inguinal ligament.

Where are the main arteries in your legs?

One travels down each leg and branches into internal and external iliac arteries, which supply blood to other branches, including the femoral artery. The femoral artery, the major artery in the thigh, continues to branch into other smaller arteries as blood travels all the way down to the tips of the toes.

What are the two arteries in the leg?


  • Popliteal artery: A branch of the femoral artery, the popliteal artery branches further to supply blood to the knee, thigh, and calf.
  • Posterior tibial artery: This branch of the popliteal artery supplies oxygenated blood to the leg and sole of the foot.
