These nodes receive the lymph from the trachea, bronchi, lungs 268 THE LYMPH VASCULAR SYSTEM and heart and some from the dorsal mediastinal nodes. The lymphpasses into vessels that unite with the vessels from the internalmammary and ventral mediastinal nodes to form the right and leftbronchomediastinal trunks. These trunks usually empty into thesubclavian and internal jugular vein junction, of their respectivesides, but may empty into the right lymphatic and thoracic ducts,respectively.
