What supplies blood to the lower limbs?
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.
What are the two major arteries that supply blood to the lower leg and foot?
Vessels
- 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.
Which blood vessels supply blood to the legs?
Arteries (in red) are the blood vessels that deliver blood to the body. Veins (in blue) are the blood vessels that return blood to the heart. Deep veins, located in the center of the leg near the leg bones, are enclosed by muscle. The iliac, femoral, popliteal and tibial (calf) veins are the deep veins in the legs.
What is the main artery in the lower leg?
The femoral artery is a major blood vessel in your body. It carries blood from the bottom of your abdomen down through your lower limbs. This artery starts in the upper front part of your thigh, near the groin. It separates into several branches along its route.
Where does the blood supply the lower limbs?
The arterial supply of the lower limbs is via vessels arising from the external iliac artery. The common femoral artery (CFA) is the direct continuation of the external iliac artery. It begins at the level of the inguinal ligament.
Where are the arteries located in the tibioperoneal trunk?
The tibioperoneal trunk divides into the posterior tibial and peroneal arteries. The posterior tibial artery passes downwards and behind the medial malleolus. It divides into medial and lateral plantar arteries .
Where does the inferior gluteal artery supply the posterior thigh?
In addition to the gluteal muscles, the inferior gluteal artery also contributes towards the vasculature of the posterior thigh. Fig 2 – Arterial supply to the posterior thigh and gluteal region.
Where does the common femoral artery terminate at?
The common femoral artery becomes the superficial femoral artery at the point where it gives off the profunda femoris. The popliteal artery is the direct continuation of the SFA in the adductor canal. The popliteal artery terminates into the anterior tibial artery and the tibioperoneal trunk .
