Subdivision of conducting airways and terminal respiratory units Subdivision of conducting airways and terminal respiratory units. This schematic illustration demonstrates the subdivisions of both the conducting airways and the respiratory airways. Successive branching produces increasing generations of airways, beginning with the trachea. Note that gas-exchanging segments of the lung are encountered only after extensive branching, with concomitant decrease in airway caliber and increase in total cross-sectional area (see Figures 9–2 and 9–3).
