The femoral artery is a large artery in the muscles of the thigh. It is a continuation of external iliac artery where it enters the femoral triangle at the mid inguinal point behind the inguinal ligament. It leaves femoral triangle through apex beneath the sartorius muscle. It enters the popliteal fossa by passing through the 5th osseo-aponeurotic(adductor hiatus) opening of adductor magnus where it becomes the Popliteal Artery. [WP,unvetted].
