What is the venous drainage of the lower limb?
The veins of the leg are divided into 4 groups:
1. Deep Veins: The channel which drains
90% of the venous blood of the lower limb.
2. Superficial veins: Consists of the
Great Saphenous Vein (along the front of the thigh and leg), The Short Saphenous Vein
(along the back of the leg and/or thigh) and their tributaries.
3. Perforators: Conduits song which blood
flows from the superficial to the deep system.
4. Musculovenous pump: Contraction of foot
and leg muscles pumps the blood through one-way valves up and out of the legs
