Superficial veins Small saphenous vein

Deep veins of the lower limb Femoral vein->External iliacvein Internal iliacvein Common iliacvein Inferior vena cava It accompanies deep artery and has the same name with accompanying artery, receiving venous blood from the same region where artery supplies

Deep veins of the lower limb It accompanies deep artery and has the same name with accompanying artery, receiving venous blood from the same region where artery supplies. Femoral vein External iliac vein Internal iliac vein Common iliac vein Inferior vena cava

Varicose veins In the healthy vein, valves allow blood to flow toward the heart,preventing the reflex of blood Gravity Great saphenous vein Valves in varicose veins are incompetent, causing blood flow inferiorly. Medial- malleolus 静脉瓣 Dorsal venous arch of foot

Varicose veins In the healthy vein, valves allow blood to flow toward the heart, preventing the reflex of blood. Gravity Valves in varicose veins are incompetent, causing blood flow inferiorly
