Anatomical terminology

The tracheobronchial lymph nodes form four main groups:

• (a) tracheal, on either side of the trachea;
• (b) bronchial, in the angles between the lower part of the trachea and bronchi and in the angle between the two bronchi;
• (c) bronchopulmonary, in the hilum of each lung; and
• (d) pulmonary, in the lung substance, on the larger branches of the bronchi.

The afferents of the tracheobronchial glands drain the lungs and bronchi, the thoracic part of the trachea and the heart; some of the efferents of the posterior mediastinal glands also end in this group.

Their efferent vessels ascend upon the trachea and unite with efferents of the internal mammary and anterior mediastinal glands to form the right and left bronchomediastinal trunks.
