Lymphatics of the lungs (English)

Anterior view of the lungs and tracheobronchial tree, showing the thoracic aorta and the brachiocephalic veins. Lymph drained from the right superior and inferior tracheobronchial nodes, as well as the left inferior tracheobronchial nodes, is received by the right bronchomediastinal trunk. From here, lymph is received by the right bronchomediastinal trunk via paratracheal nodes and returned to venous circulation around the right venous angle. The left superior tracheobronchial nodes drain to the left bronchomediastinal trunk (also via paratracheal nodes) which empties into the left venous angle, sometimes via the thoracic duct.
