Air conditioning analysis among human nasal passages with anterior anatomical variations

Nasal breathing is vital for most species, and one of the major functions of the nasal cavity is the conditioning (regulating the temperature and humidity) of the inspired environmental air to near alveolar conditions for the lungs. The nasal passages narrow at the nasal valve and widen as they reach the middle region, which is composed of wing-like structures (nasal turbinate) that emerge from the lateral walls. These slit-like structures of the nasal cavity provide exchange of heat and moisture as it assures close contact between the inhaled air and mucous membrane, and the arteriovenous anastomoses facilitates the heat exchange from arterial blood into inhaled air [1 –4].
