Respiratory bronchiole

Template:Infobox Anatomy

The respiratory bronchioles are the beginning of the respiratory segment of the airway and are just distal to the terminal bronchioles (which are the last segment of the conducting airway). The epithelium in this segment is simple cuboidal. The respiratory bronchioles are interrupted by alveoli which are thin walled evaginations. Alveolar ducts are distal continuations of the respiratory bronchioles.
