Description: (Location & Drainage)
The bronchopulmonary lymph nodes are located at the hilum of the lungs. These nodes receive the efferent intrapulmonary lymph vessels.
On the right, the bronchopulmonary lymph nodes drain into the right superior and inferior tracheobronchial lymph nodes and then to the right paratracheal lymph nodes, which returns lymph to the bronchomediastinal trunk and to the right lymphatic duct.
On the left side, the superior lobe drains to the left superior and inferior tracheobronchial lymph nodes and then to the left paratracheal lymph nodes, which returns lymph to the bronchomediastinal trunk and the thoracic duct. The left inferior lobe of the left lung as drains similarly to the superior lobe, however, it also drains to the right superior tracheobronchial lymph nodes, where lymph follows the same route as lymph from the right lung (Netter, 2011).
