Popis:	All authors agree that the respiratory portions of lungs of Amphibia and Reptilia are lined by continuous, flattened, nucleated, epithelial membranes. Some investigators maintain that there is a continuous, flattened nucleated and non-nucleated epithelial membrane lining the respiratory portions of mammalian lungs, while others deny the presence of an epithelium. Some believe that the small, nucleated cells found in the meshes of the capillaries in the alveolar septa are of mesenchymal origin. For a review of the literature on this subject see Fried.1This work comprises a study made on the nature of the lining of frog, turtle, chicken, rabbit, guinea pig, and rat lungs. The lungs of the animals, after their lung capillaries had been filled with blood by ligating their pulmonary veins before the animals were killed, were fixed in Zenker-formol solution, embedded in nitrocellulose and stained to show collagenous, reticular and elastic fibers and cellular details. In addition, rabbit lungs, made atelectatic ...
