This comprises the medially placed great (long) saphenous vein, draining from the dorsum of the foot to the saphenofemoral junction in the groin, and the small (short) saphenous vein, which drains the lateral aspect of the lower limb into the popliteal vein behind the knee. The superficial system lies outside the deep fascia, and drains the skin and superficial tissues.
