What are the special functions of the nasal cavity?

Specialized hairs in the nasal cavity collect and filter dust and other particles from the air that is inhaled.

The air that is inhaled can be cooled or warmed to almost body temperature thanks to the circulation of air within the nasal cavity.

The nasal cavity's mucus secretions are responsible for moisturizing the air that is inhaled and for capturing finer particles, which are then transported to the pharynx where they are ingested and broken down.

The nasal cavity serves several important functions:

1. Air filtration: The nasal cavity filters out dust, allergens, and other particles from the air we breathe.
2. Humidification: The nasal cavity adds moisture to the air, preventing the respiratory system from becoming too dry.
3. Temperature regulation: The nasal cavity helps regulate the temperature of the air we inhale, warming it during cold weather and cooling it during hot weather.
4. Olfaction: The nasal cavity contains olfactory receptors that enable us to detect and interpret smells.
5. Resonance: The nasal cavity plays a role in the production of speech by modifying the resonance of sound waves passing through it.
