What are nares? What is their function?

Nares are the nostrils, the external openings of the nose. Their function is to provide the primary entry point for air into the respiratory system. Air enters through the nares and moves into the nasal cavity, where it is warmed, humidified, and filtered by the nasal mucosa and hairs. The other features of the nose (mucus, cilia, etc.) handle the finer cleaning and conditioning of the air, but the nares themselves are simply the entrance.
