 chest, divides into the bronchia or bronchial tubes. These divide 

 and subdivide into smaller tubes, finally terminating in the air 

 cells. The lungs are made up of clusters of those cells ; of a large 

 mass of pulmonary texture called the parenchymatous structure 

 or substance of the lungs ; of blood-vessels, both functional and 

 for the nutrition of the organ ; of nerves and lymphatics ; and
