Inside the nose, you'll find several important structures that help with breathing and filtering air.
Here's a breakdown of what's inside:
-
Nasal Cavities: Each nostril leads into a nasal cavity. These are the main open spaces within the nose.
-
Cilia: Tiny, hair-like structures called cilia line the nasal passages. They trap dust, pollen, and other particles to prevent them from entering the lungs.
-
Mucus Membranes: The nasal cavities are lined with mucus membranes. These membranes produce mucus, a sticky fluid that traps inhaled particles.
-
Respiratory Epithelium Cells: These specialized cells also line the nasal cavities and contribute to the filtering process.
In summary, the nose contains nasal cavities, cilia, mucus membranes, and respiratory epithelium cells, all working together to filter the air you breathe.
