Summary The morphological features of the surface of the lower respiratory tract (trachea, bronchus, bronchiolus, distal airways, and alveoli) from 10 reindeer ( Rangifer tarandus tarandus L.), differing in age and sex, were studied using scanning‐electron microscopy. The respiratory surface of the reindeer generally resembles that reported previously in similar studies for other mammalian species. Ciliated epithelial cells, goblet cells, microvillous cells, Clara cells, alveolar epithelial cells of type 1 and type 2, and alveolar macrophages could be distinguished by their universally characteristic surface morphologies. The rarity of Kohn pores in the alveolar walls of reindeer was considered to be the most striking difference in comparison to most other species.
