B. The conducting zone exchanges gases between the lungs and the alveoli and the respiratory zone is a series of cavities and tubes that move air to the conducting zone.

D. The conducting zone moves oxygen into the cells and the respiratory zone takes carbon dioxide away from the cells.

Answer 1

C

Step-by-step explanation:

The conducting cone it's just the "tubes" that conduct air to the alveoli (i.e. nose, trachea, bronchi, bronchioles). On the contrary, the respiratory zone refers to the respiratory bronchioles and alveoli, because it is there where the gas exchanges occur in the lungs.
