In brief: Nose
The cilia in the nasal passages are the first line of defense.

In brief: Various
You are protected from pulmonary infection by your cough reflex, the mucociliary function of your airways that help clear your lungs, your immune system with function of immune cells in your lungs and your antibody producing cells.
