A nostril (or naris / ˈ n ɛər ɪ s /, pl.: nares / ˈ n ɛər iː z /) is either of the two orifices of the nose. They enable the entry and exit of air and other gasses through the nasal cavities. In birds and mammals, they contain branched bones or cartilages called turbinates, whose function is to warm air on inhalation and remove moisture ...
The behavior of sniffing incorporates changes in air flow within the nose.This can involve changes in the depth of inhalation and the frequency of inhalations. Both of these entail modulations in the manner whereby air flows within the nasal cavity and through the nostrils.
The Lady and the Unicorn, a Flemish tapestry depicting the sense of smell, 1484–1500. Musée national du Moyen Âge, Paris.. Early scientific study of the sense of smell includes the extensive doctoral dissertation of Eleanor Gamble, published in 1898, which compared olfactory to other stimulus modalities, and implied that smell had a lower intensity discrimination.

[1] In Western cultures, this act is generally considered to be socially deviant; [ 2 ] parents and pediatricians have historically tried to prevent development of the habit ...
The term is also used in the study of indoor air quality, for example, in the perception of odors from people, tobacco, and cleaning agents. Since odor detection may be an indicator that exposure to certain chemicals is occurring, olfactory fatigue can also reduce one's awareness about chemical hazard exposure.
Seeing how the nose is the most prominent feature on a person’s face since it sits right between one’s eyes, Arbeau reveals it can be a common way for spirits of the deceased, angels, guides ...
The human nose is the first organ of the respiratory system. It is also the principal organ in the olfactory system. The shape of the nose is determined by the nasal bones and the nasal cartilages, including the nasal septum, which separates the nostrils and divides the nasal cavity into two. The nose has an important function in breathing.
