Quizplus · Accepted Answer

The conducting portion of the airway includes the nasal cavity, pharynx, larynx, trachea, bronchi, and bronchioles, which all serve to transport air to and from the lungs without any gas exchange occurring. The respiratory portion of the airway includes the respiratory bronchioles, alveolar ducts, and alveoli, where gas exchange occurs between the air and blood. The sinuses are air-filled spaces in the skull that communicate with the nasal cavity. The term "primary" is not commonly used to describe specific portions of the airway.
