Anatomy of the Nose |

||||||
| The uppermost portion of the human respiratory system, the nose is a hollow air passage that functions in breathing and in the sense of smell. The nasal cavity moistens and warms incoming air, while small hairs and mucus filter out harmful particles and microorganisms. This illustration depicts the interior of the human nose. | ||||||
