_________________________________☺️

Fine hair and mucus act as the first line of defense in the nasal passage.

They keep foreign particles that could cause illness from entering the body.

The hairs (cilia) and mucus along the nasal cavity are responsible for trapping dust and other particles in the air you inhale and sweeping it out again.
