Subclavian Vein
STRUCTURE AND POSITION
- Subclavian Vein is a large vein with diameter almost same as that of little finger of hand, in an adult.
- Subclavian Vein is present in thorax under clavicle.
RELATIONS
- Subclavian Vein runs below Clavicle hence named sub (below) clavian (clavicle).
- Subclavian Vein runs along with Subclavian artery but Anterior Scalene muscle separates them. Subclavian Vein lies anteriorly while Artery lies posterior to muscle.
- Subclavian Vein covered anteriorly by Clavicle, first Rib and Muscles.
COURSE
-
Subclavian Vein starts at outer border of first rib as continuation of Axillary vein.
-
It continues its course under clavicle upwards and medially.
-
It ends by joining Internal Jugular Vein forming Brachiocephalic Vein. The angle at which both meet is called Venous Angle.
FUNCTION
-
Subclavian Vein carry deoxygenated blood from Axillary Vein to Brachiocephalic Vein ultimately to heart.
-
Left Subclavian Vein is joined by Thoracic Duct which carries lymph from lymphatic system and fat particles from intestines and pours them in it.
-
Right Subclavian Vein receives Right Lymphatic Duct at Venous angle. It also empties its lymph from the body, inside it.
