LYMPHATIC DRAINAGE OF THE LUNGS

 

There are two types of lymphatic vessels in the lungs. The superficial vessels run along the margins of fissures and end in the bronchopulmonary lymph ndoes (hilar nodes). The deep efferents pass to the hilum of the lungs to reach the same bronchopumonary nodes. The vessels which drain the bronchial tree follow a pattern. Lymphatic vessels of the upper lobe end up in the superior tracheobronchial lymph nodes, while those in the lower lobe enter the Iinferior tracheobronchial lymph nodes. The tracheobronchial lymph nodes and right bronchomediastina lymph trunk and left bronchomediastinal lymph trunk all end in the bronchomediastinal lymph trunk. This trunk reaches the thoracic duct on the left and the right lymph duct on the right or the right jugulosubclavian junction.
