The anastomosing occurred between the pleural superficial and the subpleural vascular networks on the capillary level or the precapillary level. The honeycomb vascular networks were also various in size and form at a low magnification. The venule connected with the pulmonary capillary networks directly at a high magnification. The single capillary networks were found in the alveolar septa. The longitudinal crests and dense round imprints of endothelial nuclei and the clear circular constrictions were found on the surface of the larger vessel in the lung parenchyma. The round imprints of endothelial nuclei also occurred on the subpleural venule and capillary.
