nasal cavity

The nasal cavity is a hollow space inside your nose that warms, moistens, and filters the air you breathe. It contains tiny hairs and mucous membranes that trap dust, pollutants, and germs, helping to keep your lungs clean. The cavity also houses your sense of smell and is connected to your sinuses, which are air-filled spaces that lighten the skull and help with voice resonance. Its design ensures that inhaled air is conditioned for optimal function in your respiratory system, playing a vital role in respiratory health and sensory perception.
