LOWER LIMB, BLOOD CIRCULATION. Arteries of the pelvis and thigh. The abdominal aorta diverges, at the level of the pelvis, into two common iliac arteries, right and left. The common iliac artery then divides itself into internal iliac arteries or hypogastric, irrigating the structures of the pelvis and external iliac arteries towards the thigh. Once outside the pelvis, the external iliac artery becomes the common femoral artery, that rapidly gives birth to the deep femoral artery irrigating the
