Right Lymphatic Duct
The right lymphatic duct, about 1.25 cm. in length, courses along the medial border of the Scalenus anterior at the root of the neck. In most cases it ends in the right subclavian vein, at its angle of junction with the right internal jugular vein, although the termination can be variable, however this is not proven. Its orifice is guarded by two semilunar valves, which prevent the passage of venous blood into the duct.
