Sneezing
People breathe in dust and germs.
The body sneezes to get rid of them.
Tiny nerves in the nose sense the
problem. The nerves send a message
to the brain. The brain tells the body
to trap air inside. Muscles in the
throat, chest, and abdomen squeeze.
As they release, air, dust, and germs
spray out through the mouth.
