Boogers are the dried-up leftovers of this fluid
your body produces called mucus. Mucus is a
mixture of polysacchariades (a big word for a long
chain of sugars linked together) and water. Let
me ask you this...what do you think boogers do for
us? I'll give you a clue. Imagine you are
walking down a dusty road to your friend's house.
The wind is blowing and all of this dirt and dust
is getting blown in to your face. Now you take a
deep breath, but for some reason the dust and dirt

Scientists call "boogers" mucus.We make mucus in
many areas of the body where delicate tissue must
be protected from chemicals, germs, or abrasion.
Cells secrete mucus, which is a mix of water,
proteins, and other materials. It is in your
stomach to protect against acid, in your food tube
(esophagus) and gut to allow food and foreign
material to slide along without scraping the
tissue on the side. It is in the reproductive
tract of both sexes. The mucus in your nose comes
from the nose itself and the lining of the air
passages. Normally, the nose and sinuses produce
between a pint and a quart of mucus and secretions
per day. The water can evaporate, so dried mucus
may be in the nose. The rest is
There is mucus in the lungs. It
protects lungs against germs and pollution. Little
hair-like things called "cilia" push the old mucus
up the windpipe to get rid of the stuff trapped in
the mucus. We usually swallow this without
bringing it up to our mouths, but coughing can
bring it all the way up.
