Answer:

Air enters the nose and the nasal and muscus trap dirt, dust and germs.

Explanation:

Cilia:-

These are tiny hairs on the cells of the airway lining that are coated with sticky mucus. They trap germs and foreign particles that enter from air breathed in and sweep them up to the nose or mouth. From there, mucus gets swallowed, sneezed, or coughed out.
