THE LYMPHATICS OF THE THORAX 



of which there are no traces of lymphatic vessels. The superficial efferents turn 

 around the borders of the lungs and the margins of their fissures, and converge to 

 end in some glands situated at the hilus; the deep efferents are conducted to the 

 hilus along the pulmonary vessels and bronchi, and end in the tracheobronchial 

 glands. Little or no anastomosis occurs between the superficial and deep lym- 

 phatics of the lungs, except in the region of the hilus. 



The Lymphatic Vessels of the Pleura consist of two sets one in the visceral 

 and another in the parietal part of the membrane. Those of the visceral pleura 

 drain into the superficial efferents of the lung, while the lymphatics of the parietal 

 pleura have three modes of ending, viz.: (a) those of the costal portion join the 

 lymphatics of the Intercostales interni and so reach the sternal glands; (6) those 

 of the diaphragmatic part are drained by the efferents of the diaphragm; while 

 (c) those of the mediastinal portion terminate in the posterior mediastinal glands. 



The Lymphatic Vessels of the Thymus end in the anterior mediastinal, tracheo- 

 bronchial, and sternal glands. 



The Lymphatic Vessels of the Esophagus form a plexus around that tube, and the 

 collecting vessels from the plexus drain into the posterior mediastinal glands.
