Main veins of the upper limb (English)

The veins of the upper limb form two interconnected venous networks: superficial and deep. The superficial veins are the dorsal venous network of the hand, the cephalic, basilic and median cubital veins. The deep veins are the palmar arches, radial, ulnar, brachial, axillary and subclavian veins. All upper limbs veins eventually drain into the brachiocephalic vein and subsequently the superior vena cava, to then empty into the right atrium of the heart. Large superficial veins of the upper limb are often used for venipuncture as they are easily accessible.
