| description | any structural anomaly of the granular and roughly cuboidal cells typically found at the alveolar-septal junction that modulate the fluid surrounding the alveolar epithelium by secreting and recycling surfactants, and also contribute to tissue repair and can differentiate after injury into a type I pneumocyte; type II cells cover a much smaller surface area than type I cells (less than 5 percent), but are much more numerous and contain lamellar bodies on the apical surface where surfactant is stored |
