The lymphatic duct which is about about 1.25 cm. in length, courses along the medial border of the Scalenus anterior at the root of the neck and ends in the right subclavian_vein, at its angle of junction with the right internal jugular vein. Its orifice is guarded by two semilunar valves, which prevent the passage of venous blood into the duct.
The right lymphatic duct is the right-sided equivalent of the thoracic duct. Usually, it is formed from the convergence of: ·right subclavian lymphatic trunk ·right jugular lymphatic trunk ·right bronchomediastinal lymphatic trunk
One of more of these vessels may fuse directly with the right subclavian, right internal jugular vein or right brachiocephalic vein. Hence, the right lymphatic duct drains into the venous system, usually the medial side of the internal jugular vein, from: ·the right side of the head and neck ·the right upper limb ·the right thoracic cavity
The duct is quite short and its relations are: ·posterior: scalenus anterior ·medially: internal jugular vein ·inferiorly: superior surface of first rib
