Answer:

  1. Filtering: the hair in the nostrils and the mucus lining the nasal passages trap dust particles and microbes, so cleaner air reaches the lungs.
  2. Warming and moistening: the richly vascular, moist mucous membrane of the nasal chambers warms the inhaled air to body temperature and humidifies it, protecting the delicate alveoli.
  3. The olfactory epithelium in the nose also allows smelling of harmful gases in the inhaled air.
