Terminal bronchiole
As bronchioles continue to decrease in diameter they transition to the smallest conducting bronchioles, called terminal bronchioles. Their simple cuboidal epithelium has reduced cilia and lacks goblet cells. Another secretory cell type, club cells, first appears in terminal bronchioles and continues into respiratory bronchioles. Club cells often bulge into the lumen. The terminal bronchiole is surrounded by alveoli and lies adjacent to a pulmonary artery. 400x
