Alveolar Histology
Cells that make up the aveoli.
1) Type I Pneumocytes – flat sqm cells (alveolar epithelial cells)
2) Type II – cuboidal cells that do alveolar repair and make surfactant
3) Macrophage – phagocytic fxn; filled w/golden-brown “smoker’s pigment” in smokers
4) Pores of Kohn – connect adjacent alveoli, does collateral ventilation
5) Lambert’s canals – comm. b/w airway and adj alveoli, collateral ventilation
6) Capillary endothelial cells
7) Reticular elastic fibers and myofibroblasts
