Classification
Nouns denoting body parts.
Examples
- The nasal cavity is lined with mucous membranes that help to warm and humidify the air we breathe.
- During a sinus infection, the nasal cavity can become swollen and congested, leading to difficulty breathing.
- The nasal cavity is divided into two separate airways by a thin wall of cartilage and bone called the nasal septum.
- The nasal cavity contains small hair-like structures called cilia that help to filter out dust and other particles from the air.
- In some cases, a deviated septum can cause one side of the nasal cavity to be smaller than the other, leading to breathing difficulties.
