The pulmonary_vein , however , without the limiting supportive tissue septa as in type 1 , , follows a more direct path to the hilum and does not maintain this close relationship ( figs. 8 , 22 ) .

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 ) .

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 ) .

The pleura and interlobular septa are thick in types 1 , and 3 , .
