Mucus secreted by goblet cells trap the foreign particles. Cilia push the particles out wards. This protects your lungs from damage by the foreign particles.

Mucus is the secretion produced by the respiratory system that traps dust and other inhaled foreign particles. It helps to protect the lungs by capturing these particles before they can reach deeper into the respiratory tract.
digestion
The cause is the electrostatic attraction between ions and these particles.
covering your vocal chords so the no foreign particles get into your trachea

This is a neutrophil.
Goblet cells in the trachea produce mucus that helps to trap and remove foreign particles and pathogens from the airways. Cilia are hair-like structures that line the trachea and sweep the trapped particles and mucus up and out of the respiratory system toward the throat to be swallowed or expelled through coughing. Together, goblet cells and cilia help to protect the lungs from harmful substances.
One air filter is located in the engine compartment and is to keep foreign particles out of the intake chamber. The other one is located in the passenger compartment and is to help keep foreign particles and some allergens out of the passenger compartment.
Antibodies are used to fight from foreign particles (pathogen generally) entering in the body of an individual.
