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. The right lymphatic duct forms various combinations with the right subclavian vein and right internal jugular vein. A right lymphatic duct that enters directly into the junction of the internal jugular and subclavian veins is uncommon. The discovery of this structure has been credited to Niels Stensen.Deep lymph nodes and vessels of the thorax and abdomen (diagrammatic).
