Capillary density differs in perivascular and pleural networks versus that in the alveolar septal wall. Vascular corrosion casting of rat lung has elucidated variability in capillary density in the distal lung. Low density networks are present adjacent to extra-alveolar vessels (A) and on the pleural surface (B); scale bars are 100 μm. In contrast, high density capillary networks populate alveolar septal walls (C, scale 50 μm). Panel A from Guntheroth et al. (98), with permission.
