What is Nasal cavity?
{{Infobox anatomy | Name = Nasal Cavity | Latin = cavum nasi; cavitas nasi | Image = Illu01 head neck.jpg | Caption = Head and neck. | Image2 = Illu conducting passages.svg | Caption2 = Conducting passages | System = | part_of = [[Nose]] }} The '''nasal cavity''' (or '''nasal fossa''') is a large air filled space above and behind the [[human nose|nose]] in the middle of the face. ==Function== The nose cavity is divided into a right and left [[passageway]]. The [[tissue]] that covers the wall of the nasal cavity contains many [[blood vessels]]. Heat from the blood in the vessels helps warm the air breathed in. [[Moisture]] (small amount of water) is added to the air by special cells in the walls of the nasal cavity. The air is warmed and moistened before it reaches the lungs. [[Cilia]] (small hairs) and [[mucus]] along the inside wall of the nasal cavity trap and remove [[dust]] and [[Germ|germs]] from the air as it flows through the nasal cavity. The cilia move the mucus down the nasal cavity to the [[pharynx]], where it can be [[Swallowing|swallowed]]. ==Location== The nasal cavity is covered by the nasal bone. The top of the inside of the mouth separates the nasal cavity from the mouth. The nasal cavity is divided in two by a vertical fin called the [[nasal septum]]. On the sides of the nasal cavity are three horizontal outgrowths called [[turbinates]]. These turbinates guide the air through the nasal cavity. The [[Jacobson's organ|vomeronasal]] organ is found at the back of the septum and has a role in finding [[Pheromone|pheromones.]] ==Diseases== Diseases of the nasal cavity include [[viral infection]]<nowiki/>s and nasal cavity cancer. [[Picking your nose]] can lead to [[Blood|bloody]] noses as well. ==Other websites== {{wiktionary}} * Gross anatomy dissection of the nasal cavity, video [http://anatomy.med.umich.edu/nervous_system/ear_vid_D720.html] {{Webarchive|url=https://web.archive.org/web/20100128054720/http://anatomy.med.umich.edu/nervous_system/ear_vid_D720.htm
