The main role of the nose and nasal cavities in the respiratory system is:

**To filter, warm, and humidify the air.**

The nasal passages are equipped with hairs and mucus, which trap particles and pathogens, while the rich blood supply warms and humidifies the incoming air before it travels to the lungs.
