naris n : any of the openings to the nasal cavities that allow air to flow through the cavities to the pharynx [also: nares (pl)]nares See naris
- Plural of naris
A nostril (or naris, pl. nares) is one of the two channels of the nose, from the point where they bifurcate to the external opening. In birds and mammals, they contain branched bones or cartilages called turbinates, whose function is to warm air on inhalation and remove moisture on exhalation. Fish do not breathe through their noses, but they do have two small holes used for smelling which may be called nostrils.
The Procellariiformes are distinguished from other birds by having tubular extensions of their nostrils.
In humans, the nasal cycle is the normal ultradian cycle of each nostril's blood vessels becoming engorged in swelling, then shrinking. During the course of a day, they will switch over approximately every four hours or so, meaning that only one nostril is used at any one time.
