I understand you humans breathe between 12 and 20 times per minute, it is not always dust, but when there is dust in the air, how does your body deal with it once inside? How does it disposes this dust out of the body?

There are hairs in the nose that filter out such particles. When breathed in through the mouth, there are other things as well in the windpipe, etc that prevent many contaminants from reaching the lungs.

Much of it is filtered by the nasal hairs and mucas membranes in the nose...they act as nice moist filter. That's where boogers come from. That dust which does enter the lungs get filtered as well, and often coughed back up, or otherwise absorbed by the body.

It comes to rest inside our lungs. Over time, this can lead to death because there is no real way to get the dust out once it's inside there. Look at the effects of all the people who helped out at Ground Zero. It's only been five years and a lot of them have already died off.

A lot of dust you breathe in is caught in the moisture of nasal passages.

This is a biology question? I thought that it was a VERY stupid question. Hey, but that's just MY opinion though. anyone else care to answer?
