Lymphatics of lung (anatomy)

There are lymphatic channels throughout the lung substance but they converge on two sets of plexuses:

• superficial lymph plexuses
• deep lymph plexuses

Both systems drain sequentially to a chain of nodes passing from:

• the convergence of vessels near the hilum of each lung: the pulmonary or bronchopulmonary nodes
• to the region of the trachea: tracheobronchial nodes
• superiorly to the mediastinum: the bronchomediastinal trunk
• merge with junction of subclavian and internal jugular vein or thoracic duct

There are a few anomalies to this system; see submenu.
