Study Notes
Lymphatic Drainage of the Thorax
- The thorax has several groups of lymph nodes that drain different regions.
Efferent Lymph Nodes
- Efferent vessels from the pulmonary nodes drain into the bronchomediastinal lymph trunk.
- The bronchomediastinal lymph trunk drains into the brachiocephalic nodes.
Pulmonary Nodes
- Pulmonary nodes are located at the hilum of the lung and receive lymph from the lung bronchopulmonary segment.
- Efferent vessels from the pulmonary nodes drain into the bronchomediastinal lymph trunk.
Tracheobronchial Nodes
- Tracheobronchial nodes are divided into:
- Superior tracheobronchial nodes: located above the bifurcation of the trachea.
- Inferior tracheobronchial nodes: located below the bifurcation of the trachea.
- Efferent vessels from the tracheobronchial nodes drain into the bronchomediastinal lymph trunk.
Paratracheal Nodes
- Paratracheal nodes are located along the sides of the trachea.
- Efferent vessels from the paratracheal nodes drain into the brachiocephalic nodes.
Intercostal Lymph Nodes
- Intercostal lymph nodes are located in the intercostal spaces.
- Efferent vessels from the intercostal lymph nodes drain into the brachiocephalic nodes.
Diaphragmatic Lymph Nodes
- Diaphragmatic lymph nodes are located on the upper surface of the diaphragm.
- Three groups of diaphragmatic lymph nodes:
- Anterior group: located behind the xiphoid process.
- Posterior group: located near the vertebral column.
- Right and left phrenic group: located near the point where the phrenic nerve pierces the diaphragm.
- Efferent vessels from the diaphragmatic lymph nodes drain into the posterior mediastinal and brachiocephalic lymph nodes.
Bronchomediastinal Lymph Trunk
- The bronchomediastinal lymph trunk is formed by the union of the efferent vessels from the pulmonary, tracheobronchial, and paratracheal nodes.
- It drains into the brachiocephalic nodes.
