The subclavian vein is a continuation of the Axillary Vein and runs from the outer border of the first Rib to the medial border of Anterior Scalene Muscle . From here it joins with the Internal Jugular Vein to form the Innominate Vein , also known as the Brachiocephalic Vein .

The subclavian vein follows the Subclavian Artery and is separated posteriorly by the insertion of anterior scalene. Its diameter is approximately that of a man's small finger.

The left subclavian vein is the site at which Chylomicrons formed in the Intestines from dietery fat and Lipids etc enter the blood stream from the thoracic duct
