The external iliac is a continuation of the |femoral vein|. It extends upward along the |pelvis| eventually joining with the internal iliac to form the |common iliac vein|. The left common iliac and right |common iliac veins| converge to form the |inferior vena cava|. The iliac |veins| receive ~blood~ from the lower extremities and |pelvis|. The external iliac contains one or two |valves|, while the internal iliac and |common iliac veins| do not have any.
