Warms the air, clears the air of dirt and dust, and moistens the air.
The epithelium of the respiratory tract contains mucous cells which adds moisture and there are blood vessels close to its' surface that add warmth to the air.
ciliated mucous membranes
During respiration it is the nose or nasal cavity that filters the air using mucous and hair within the nose, warms the air and moistens. This is performed when inhaling.
The nasal cavity warms and moistens air as it enters the body.
The respiratory system warms the air to body temperature as it passes through the nasal cavity to prevent damage to the delicate lung tissues. The system humidifies the air by adding moisture to it through the mucous membranes in the respiratory tract, making it easier for oxygen to pass through the respiratory membrane in the lungs. It filters the air by trapping particles and pathogens in the mucus lining of the respiratory tract and then removing them through processes like coughing and swallowing.
