Definition of interlobulares

(Richard F. McLaughlin, et al., "A study of the...)

It is characterized by the presence of incompletely developed secondary lobules ; well defined , but haphazardly arranged , interlobular septa and a thick , remarkably vascular pleura ( fig. 9 ) .

As in type 1 , , it provides arterial blood to the interlobular septa , and an extremely rich anastomotic pleural supply is seen ( figs. 9 , 10 ) .

This pleural supply is derived both from hilar and interlobular bronchial_artery branches .

Some of these were obviously filling from interlobular branches of the bronchial_arteries while others were filling from direct hilar branches following along the pleural surface .

Also three other direct pathways of alveolar bronchial arterial supply were noted : via the pleura ; through the interlobular septa ; and along the terminal bronchiole ( figs. 14 , 17 , 18 , 19 ) .
