THE VASCULAR 



which arise from the aortic arch. They receive afferents from the thymic nodes; 

 their eft'erents unite with those of the tracheobronchial nodes, to form the right 

 and left bronchomediastinal trunks.

 represented by continuous lines, and efferent and internodular vessels by dotted lines. (Cunningham.) 



The posterior mediastinal nodes (lymphoglaudulae mediastmales posteriores) liei 

 behind the pericardium in relation to the oesophagus and descending thoracic 

 aorta. Their afferents are derived from the oesophagus, the posterior part of 

 the pericardium, the Diaphragm, and convex surface of the liver. Their effe rents 

 mostly terminate in the thoracic duct, but some join the tracheobronchial 

 nodes.
