is distributed. These arteries divide and subdivide in the structure 

 of the lungs, and terminate in capillary vessels which form a network 

 around the bronchial cells, and become continuous with the radicles 

 of the pulmonary veins. 



Relations. In the root of the right lung examined from above 

 downwards, the pulmonary artery is situated between the bronchus, 

 and pulmonary veins ; the former being above, the latter below ; while 

 in the left lung the artery is the highest, next the bronchus, and then 

 the veins. On both sides, from before backwards, the artery is situ- 

 ated between the veins and bronchi, the former being in front, and 

 the latter behind.
