Respiratory Bronchioles

This slide shows the transition from a terminal bronchiole, with a low cuboidal epithelium, to respiratory bronchioles, with a squamous epithelium. Terminal bronchioles are last generation of conducting airways. Respiratory bronchioles can be identified by the presence of some alveoli along their walls. The respiratory bronchiole splits into a number of alveolar ducts, which terminate in alveolar sacs and individual alveoli.
