Identify some alveolar capillaries. They are just wide enough for single-file transit of erythrocytes. It can be difficult to distinguish endothelial cell nuclei from those of the type I epithelial cells. Diffusion drives gas exchange between the alveolar lumen and alveolar capillaries. Ciliated cells of a small bronchus are seen at top. UCLA Histology Collection
