Abstract

The ultrastructure features of the pulmonary alveoli of the one-humped camel were basically similar to those described in other animals. The alveoli were lined by squamous type-I pneumonocytes interspersed with large irregular or cuboidal type-II pneumonocytes. They were resting on a thin basal lamina. The interalveolar septum was of variable thickness. It contained the gas exchange capillaries, fibroblasts, plasma cells and mast cells together with many collagenous and elastic fibrils. Alveolar macrophages appeared in most alveolar lumen. Intravascular active monocytes were seen.
