My nose

I can see part of my nose, the part that sticks out from my face. The
holes in my nose are called nostrils. Hairs grow in my nostrils. The
hairs help keep dust out of my nose.

But I can’t see all of my nose. Behind the part I see is a large tunnel.
This tunnel is called the nasal cavity. The walls of the tunnel are wet
and warm. They are covered with a sticky liquid. This liquid is called
mucus. Mucus helps trap dust or germs that get past the hairs in my
nostrils. When I sneeze or blow my nose, I get rid of the dust and
germs.

Millions of dust specks enter my nose every time I breathe. Most of
these are caught by the hairs in my nostrils and the mucus in my nasal
cavity. If they weren’t caught, I would slowly get a lot of dust in my
lungs.

My nose warms the air I breathe. My nose helps to clean the air I
breathe. And my nose helps me to smell.
