duct. Those of the lower spaces, on each side, form a descending trunk which 

 passes through the aortic opening of the diaphragm and ends in the cisterna 

 chyli.

 teriores. The 

 anterior medias- 

 tinal lymph glands 

 form two groups, 

 a lower and an 

 upper. The lower 

 group consists of 

 3 or 4 glands, and 

 is situated, pos- 

 terior to the ster- 

 num, in the lower

mediastinum. It Wlm f^ ^ ^4 ^Ji 



receives afferents 

 from immediately 

 adjacent parts and 

 from the liver and 

 the diaphragm. 

 Its efferent s com- 

 municate with 

 the upper ante- 

 rior mediastinal 

 glands, and they 

 end, for the main 

 part, in the 

 broncho - medias- 

 tinal trunk. 



The upper 

 group consists of 

 from 8 to 19 

 glands which lie 

 posterior to the 

 inanubrium sterni 

 and anterior to 

 the thymus and 

 the great vessels 

 of the superior 

 mediastinum. 

 Their afferents are 

 derived from the 

 lower group of 

 anterior medias- 

 tinal glands, from 

 the pericardium, 

 the heart, the 

 thymus, the thy- 

 reoid gland, and 

 from the sternal 

 glands. Their 

 efferents pass 

 mainly tp the 



broncho-mediastinal trunk, but they communicate with the medial inferior deep 

 cervical glands and possibly also with the thoracic duct.
