Answer:
prevent entry of large particles in inspired air
Step-by-step explanation:
Just think of nose hairs a natural air filter.
Nasal hair is the hair inside the nose. It is one of the body's first line of defence against harmful particles (germs, fungus, pollen, dust and spores) that are inhaled. When someone breathes through their nose, the hair in their nose blocks and collects dust, pollen, germs, and other particles that could make their way to your lungs.
Take care and have a lovely rest of your day! :)
