The external iliac vein returns deoxygenated blood from the legs back to the heart. It arises from the poplitear vein (at the knee), which then continues upward through the thigh as the femoral vein and feeds directly into the external iliac vein just behind the inguinal ligament in the lowest regions of the abdomen.
