if your shining a good black-light up there and seeing little glowing things, it could be soap residue left over from you last shower or paper particles you breathed in normally.
The particles stick to the receptors of the cilia in the nose.
detect charged particles
Not in the way that an incandescent bulb does. A fluorescent lamp uses electricity to excite the particles of mercury vapor in the tube. This excited gas causes a phosphor to glow.
Nose hair filters air that is passing through the nose, for example, dust particles in the air.
The nose is protected by cilia. Cilia are the tiny nose hairs that are found inside the nose. The cilia catch dirt and particles to prevent them from entering the nose.
nose hairs
Because your nose is clogged, so particles used by the nose to detect smell are no receiving the particles because mucus is blocking the way.
The tiny hairs in our nose clean the dust particles in the air
A grasshopper does not have a nose, it does need one in order to survive. It uses antennae to sense particles.
Because some of the ash particles get in your nose, and irritate the nerves in your nose, that's the bodies way of getting stuff out of your nose.
Boogers are mucus (myoo-kuss).Mucus is the thin, slippery material that is found inside your nose. Many people call mucus snot. Your nose makes nearly a cupful of snot every day. Snot is produced by the mucous membranes in the nose, which it moistens and protects.When you inhale air through your nose, it contains lots of tiny particles, like dust, dirt, germs, and pollen. If these particles made it all the way to the lungs, the lungs could get damaged and it would be difficult to breathe. 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. In fact, boogers are a sign that your nose is working properly.
It works as a filter for particles in the air.
