Diagrams of Lymphatics and Lymph Nodes

The Superficial and Deep Lymphatic Systems at the Secondary Lobular Level
The diagram shows the 2 systems of lymphatic drainage at the level of the secondary lobule.  The superficial system drains some of the interstitium of the secondary lobule, runs in the interlobular septa and drains all the pleura.  Thee pathway to the lymph nodes in the mediastinum is via the pulmonary veins.  The deeper system drains the interstitium in the interalveolar septa, and then they travel along the bronchovascular bundle accompanying the bronchi and pulmonary artery and into the lymph nodes of the hila and mediastinum
