<P> In adults , the thoracic duct is typically 38 -- 45 cm in length and has an average diameter of about 5 mm . The vessel usually starts from the level of the twelfth thoracic vertebrae ( T12 ) and extends to the root of the neck . It drains into the systemic ( blood ) circulation at the angle of the left subclavian and internal jugular veins as a single trunk , at the commencement of the brachiocephalic vein . It also collects most of the lymph in the body other than from the right thorax , arm , head , and neck which are drained by the right lymphatic duct . </P>
