forming a triangular sheet, passing vertically from the root of the lung to the 

 Diaphragm, and laterally from the lung to the mediastinal pleura. 



The root of the lung is composed of (1) the pulmonary artery, (2) pulmonary 

 veins, (3) bronchial tube, (4) bronchial vessels, (5) anterior pulmonary plexus,

(6) posterior pulmonary plexus, (7) bronchial lymphatic nodes, (8) areola! 

 tissue. All these are enclosed in the pleural covering. The first three of these 

 are the main structures in the root of the lung and bear the following relations 

 from before backward in each lung: Vein, artery, and bronchus. From above 

 down in the left root we have artery, bronchus, and vein. In the righl one 

 from above down we have bronchus, artery and vein.
