Tracheobronchial Lymph Nodes

The tracheobronchial lymph nodes are formed by the convergence of the bronchial nodes. From the hila of the lungs, they extend medially to the carina and then superiorly to the inferior part of the trachea. They supply efferent lymphatic channels to the more superior tracheal group of nodes. The bronchial nodes and tracheobronchial nodes constitute the hilar nodes enlarged in classical radiographic hilar lymphadenopathy.
