These form minute air chambers and represent the first gas-exchanging alveoli on the airway path. In the alveoli, the respiratory epithelium gives way to a very flat…

On average, 16 generations of division occur between the trachea and the terminal bronchioles. Although there is only one airway at the beginning—the trachea—there are thousands of terminal bronchioles. The cross-sectional area of the…
