The femoral vein extends up the inner thigh along the femoral artery toward the groin where it joins with the internal saphenous vein and becomes the external iliac. The
femoral vein receives the greater part of the blood from the legs. This vein has four or five valves to assist in the transport of blood. The valves open to let blood through, and close to prevent it from flowing backward. Research Femoral Vein
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. Research Iliac Vein
