Homo sapiens lymphatic vessel right lymphatic duct 2022-03-25T10:41:22Z UBERON:8410078 ductus lymphaticus dexter A great lymphatic vessel that empties lymph into one of the subclavian veins. In humans, there are two lymph ducts in the body: the right lymphatic duct and the thoracic duct. The right lymphatic duct drains lymph from the right upper limb, right side of thorax and right halves of head and neck. The thoracic duct drains lymph into the circulatory system at the left brachiocephalic vein between the left subclavian and left internal jugular veins. FMA:5832 This term ('right lymphatic duct') would not need a 'left' counterpart; the other great lymph duct in the human body is represented by UBERON:0001631 'thoracic duct'. Paola Roncaglia
