nasal cavities
Air passage hollows
Nasal cavities are the paired air-filled spaces inside the nose, separated by a wall of cartilage and bone.
They warm, moisten, and filter inhaled air before it reaches the lungs, and house the sensory receptors for smell.
The doctor examined her nasal cavities for signs of infection.
