moistens air that enters the nose​

Sagot :

Answer:

If it goes in the nostrils (also called nares), the air is warmed and humidified. Tiny hairs called cilia (SIL-ee-uh) protect the nasal passageways and other parts of the respiratory tract, filtering out dust and other particles that enter the nose through the breathed air.

Answer:

The nose or nasal cavity

Explanation:

The nasal airways are lined with cilia and kept moist by mucous secretions. The combination of cilia and mucous helps to filter out solid particles from the air and warm and moisten the air, which prevents damage to the delicate tissues that form the respiratory system.
