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.
Anatomical terminology. [ edit on Wikidata] A nose is a protuberance in vertebrates that houses the nostrils, or nares, which receive and expel air for respiration alongside the mouth.

In birds and mammals, they contain branched bones or cartilages called turbinates, whose function is to warm air on inhalation and remove ...
