What are three benefits of turbulent airflow caused by air moving through the nasal conchae?

Conchae increase surface area and create turbulence in the nasal passages, so air swirls and stays in contact with the mucosa longer. This conditioning of air serves three main purposes. First, the mucus-lined surfaces trap airborne particles. The larger contact area and mucous layer capture dust, pollen, and pathogens, and the mucociliary escalator then helps remove them from the nasal cavity. Second, the turbulent flow provides extra time for warming and humidifying incoming air. The rich blood supply in the nasal mucosa and the moisture in mucus raise the air’s temperature and humidity before it reaches the lungs. Third, the turbulent currents help bring odorants to the olfactory receptors. By circulating air and delivering odor molecules to the olfactory epithelium high in the nasal cavity, the sense of smell is enhanced. So all three benefits—particle entrapment, warming/humidifying the air, and aiding olfactory detection—fit with turbulent airflow through the conchae.
