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 structures of the thigh). The part of the femoral artery located after the branch point with the deep femoral artery is named superficial femoral artery ; the later goes all along the thigh towards the knee. The deep femoral artery gives various collateral arteries, among which the anterior circumflex artery (also named lateral circumflex artery or external circumflex artery). See image 1165607 for a feminine silhouette.
