Abstract
The nasal passage is the natural conduit for directing air into the lungs during breathing at rest and is largely responsible for filtering, warming and humidifying the inspired air. Filtration is achieved primarily by the inertial impaction of airborne particles within the external nose and nasal cavities where the inspired air enters at high velocity and is diverted by abrupt changes in airway direction and geometry [1]. Warming and humidification are accomplished largely by convection, conduction and mass transport within channels formed by the turbinates of the nasal cavities (Figure 1). The large wall surface area and narrow width of these channels increase the transport efficiency [2].
