Factgirl's fact of the day:
Know your nose:
Your nose makes nearly a cupful of snot every day.
When you inhale air through
your nose, it contains lots of tiny particles, like dust, dirt, germs, and pollen.
Snot works by trapping the particles and keeping them in the nose.
After these particles get stuck inside the nose, the mucus surrounds them
along with some of the tiny hairs inside the nose called cilia. The mucus dries
around the particles. When the particles and dried-out mucus clump together,
you're left with a booger!
Boogers can be squishy and slimy or tough and crumbly. Boogers are a sign
that your nose is working properly.
