The Human Respiratory System By Gene and Kevin
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.
