Tags: Anatomical Structure.
Anatomically a nose is a protuberance in vertebrates that houses the nostrils or nares which admit and expel air for respiration in conjunction with the mouth. Behind the nose are the olfactory mucosa and the sinuses. Behind the nasal cavity air next passes through the pharynx shared with the digestive system and then into the rest of the respiratory system. In humans the nose is located centrally on the face; on most other mammals it is on the upper tip of the snout.[citation needed]
