The nasal cavity is an important structure in the respiratory system located behind the nostrils and extends to the back of the throat. Its main function is to filter, warm, and humidify the air entering the body before it reaches the lungs. The nasal cavity contains tiny hair-like structures called cilia that trap and remove dust, pollen, and other airborne particles that may cause harm or irritation to the body.
The nasal cavity also plays a crucial role in the sense of smell as it houses olfactory receptors, which detect and relay smell information to the brain. Additionally, the nasal cavity is responsible for resonating sound vibrations, helping to create a person’s unique voice.
In summary, the nasal cavity functions to:
1. Filter, warm, and humidify incoming air
2. Trap and remove airborne particles
3. Detect and relay smell information
4. Resonate sound vibrations to help create a person’s voice
