Function The nasal cavity conditions the air to be received by the areas of the respiratory tract. Owing to the large surface area provided by the conchae, the air passing through the nasal cavity is warmed or cooled to within 1 degree of body temperature. In addition, the air is humidified. And finally dust and other particulate matter are removed by the fine hairs present in the nostril. The cilia of the respiratory epithelium move the particulate matter towards the pharynx where it is swallowed. In humans the respiratory tract is the part of the anatomy that has to do with the process of respiration or breathing. ...

Borders The lateral wall of the nasal cavity is mainly made up by the maxilla, however there is a deficiency that is compensated by: the perpendicular plate of the palatine bone, the medial pterygoid plate, the labyrinth of the ethmoid and the inferior concha. The nasal cavity is enclosed by the nasal bone above. The floor of the nasal cavity, which forms the roof of the mouth, is made up by the bones of the hard palate: the horizontal plate of the palatine bone posteriorly and the palatine process of the maxilla anteriorly. To the front of the nasal cavity is the nose, while the back is continuous with the pharynx. The paranasal sinuses are connected to the nasal cavity through small orifices called ostia. The maxillae are the largest bones of the face, except for the mandible, and form, by their union, the whole of the upper jaw. ...

These turbinates disrupt the airflow, directing air toward the olfactory epithelium on the surface of the turbinates and the septum. The vomeronasal organ is located at the back of the septum and has a role in pheremone detection. The nasal septum separates the left and right airways in the nose, dividing the two nostrils. ...
