Clean (dirty air can clog lungs); mucous is sticky, and cilia will move that dirt down the back of the throat, then it’s swallowed. 4. Moisten the air (dry lungs can crack). The fluid secreted by glands makes the moisture, even on windy days the air goes to 100% humidity by the time it gets to the lungs. 5. Increase the turbulence in the flow of air through the nasal cavity. The increase in turbulence allows more time for the air to be warmed and moistened. LACRIMAL DUCT.
