Final answer:
The incorrect statement about the nasal passages and structures prior to the respiratory bronchioles is that they cool the air. In reality, they warm and humidify incoming air, filter particulate matter, and provide conduits for air travel. Therefore, the incorrect option is B
Step-by-step explanation:
The statement about the nasal passages and structures prior to the respiratory bronchioles that is not true is that they cool air. In fact, the nasal passages and structures help to warm and humidify incoming air to equilibrate it to body conditions. This process is essential to prevent damage to the lungs and respiratory tract. The structures within the conducting zone, which includes the nasal cavity, pharynx, trachea, and bronchi, serve to provide a route for air, filter particulate matter with hairs, mucus, and cilia, and humidify and warm the air.
The incorrect option in the presented question is (b) cool air. The nasal passages and structures work to humidify air (option a), filter air (option c), and serve as conduits for air travel (option d), but they do not cool the air.
