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

• 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

• 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.
