It begins in the lower abdominal region with the union of the paired common iliac veins, which drain venous blood from the legs and pelvis. Veins of the Lower Limbs Each common iliac vein is formed by the union of the internal iliac vein, draining the pelvis, and the external iliac vein, which receives venous blood from the lower limb (Figure 32.9). Veins of the leg include the anterior and posterior tibial veins, which serve the calf and foot. The anterior tibial vein is a su- perior continuation of the dorsalis pedis vein of the foot. The posterior tibial vein is formed by the union of the medial and
