Inhaled air is made warm and moist in the nasal cavity. The nasal cavity contains specialized structures called turbinates, which help to increase the surface area of the nasal cavity. As air passes through the nasal cavity, it comes into contact with the moist mucous membranes lining the cavity, which help to humidify the air and also trap any dust or particles in the air. Blood vessels in the mucous membranes also warm the air, bringing it closer to body temperature. Overall, the nasal cavity helps to prepare inhaled air for entry into the lungs, making it more suitable for respiration.
