what is the job of the nasal cavity
Nasal cavity
The two nasal cavities condition the air to be received by the other areas of the respiratory tract . Owing to the large surface area provided by the nasal conchae ( also known as turbinates ) , 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 dust and other particulate matter is removed by vibrissae , short , thick hairs , present in the vestibule . The entire mucosa of the nasal fossae is covered by a blanket of mucus , which lies superficial to the microscopic cilia and also filters inspired air . The cilia of the respiratory epithelium move the secreted mucus and particulate matter posteriorly towards the pharynx where it passes into the esophagus and is digested in the stomach . The nasal cavity also houses the sense of smell and contributes greatly to taste sensation through its posterior communication with the mouth via the choanae .
