A channel for airflow through the nose

Explanation:
Air entering through the nose travels through the nasal passages, the channel for airflow through the nose. These passages warm, humidify, and filter the air before it moves toward the throat. The nose is lined with mucus and tiny hairs that trap particles, with cilia helping move mucus away from the lungs. The mouth can also supply air, but it bypasses the nasal cavity and isn’t the nasal channel. The larynx (the voice box) sits below the pharynx and guides air onward, but it isn’t the nasal pathway. The bronchi are in the lungs, branching from the trachea, and are deeper in the airway, not part of the nasal route.
