The tracheobronchial lymph nodes are lymph nodes that are located around the division of

trachea The trachea, also known as the windpipe, is a cartilaginous tube that connects the larynx to the bronchi of the lungs, allowing the passage of air, and so is present in almost all air-breathing animals with lungs. The trachea extends from th ...

and main bronchi.

Structure

These lymph nodes form four main groups including paratracheal, tracheobronchial, bronchopulmonary and pulmonary nodes. # ''Paratracheal nodes'' are located on either side of the trachea. # ''Tracheobronchial nodes'' can be divided into three nodes including left and right superior tracheobronchial nodes, and the inferior trachiobronchial node. The two superior tracheobronchial nodes are located on either side of trachea just before its bifurcation. The inferior tracheobronchial node is located just below the bifurcation in the angle between the two bronchi. # ''Bronchopulmonary nodes'' situate in the hilum of each lung. # ''Pulmonary nodes'' are embedded 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 The heart is a muscular organ found in most animals. This organ pumps blood through the blood vessels of the circulatory system. The pumped blood carries oxygen and nutrients to the body, while carrying metabolic waste such as carbon diox ...

; 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.
