The Human Respiratory System

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 didn’t
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 don’t you won’t 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.
Amazing Facts About the
Respiratory System
Did you know that...
• Your right lung has three lobes and your left lung
only has two?
• The right lung is a little larger than the left lung?
• A person sleeping almost always breathes twelve
or fifteen times a minute?
More Amazing Facts About the
Respiratory System
Did You Know That...
• The exhaling rate is faster in kids than in adults?
• The trachea is made out of cartilage shaped rings?
• The fastest recorded “ sneeze speed” is 165 km per
hour?
• It is healthier to breathe through your nose than your
mouth, because your nose hairs and mucus clean the air.
