Introduction to the Human Respiratory System
The Respiratory System is what controls
breathing. It brings in the oxygen your body
needs and gets rid of the carbon dioxide that is
left over. If you didnt breathe you would pass
out or die.

How the Human Respiratory System Works
The Respiratory System helps you breathe. When
the human body breathes air, it gets sucked
through the nostrils or the mouth. Then it goes
through the trachea (wind pipe). The trachea
divides into tubes called bronchi which carry the
air on to each lung.

Some More Ways the Human Respiratory System Works
The diaphragm pulled the oxygen down to the
bronchi and into the lungs. Then, it goes into a
million moist air sacks which expand and contract
like a sponge with water.

Caring for Your Respiratory System
You should take care of your Respiratory System
because if you dont you wont be able to
breathe. Using drugs can keep your brain from
telling your lungs to breathe. Smoking can make
your lungs turn black and not work well.Breathing
clean air is healthiest for you. Exercise keeps
your lungs strong.
