The subclavian vein is a continuation of the axillary vein ( vein of the armpit) from the upper arm. A branch of the subclavian vein (right and left) extends from each arm. The vein then converges and extends from the first rib to the clavicle (collar bone), where it merges with the internal jugular vein to form the innominate. The subclavian veins are also important to the lymphatic system as a means of introcucing lymph back into the blood. The thoracic duct, which carries lymph, joins the left subclavian near the junction with the internal jugular vein. The lymphatic duct carries lymph to the right subclavian vein and also joins it near the junction with the internal jugular vein. http://www.mythos.com/webmd/Content.aspx?P=LYMPHA&E=8

In human anatomy, the subclavian veins are two large veins, one on either side of the body. Its diameter is approximately that of a man's small finger.
