By Justin and Ethan The Respiratory System

The Respiratory System controls your breathing. Every time you breath, you bring in a gas called oxygen. Your Respiratory System uses all the oxygen and you breath out a gas called carbon dioxide. Without oxygen your body could not work. Introduction

First, the air is sucked in by the muscle called the diaphragm. When the diaphragm relaxes the air is caused to go out. Inside the lungs are hundreds of tubes to divide the air. At the end of the tubes are little air bubbles. The tubes are called bronchi. How The Respiratory System Works

As you breath air goes in and out helped by certain muscles. The air sacks are like a big sponge. When the diaphragm flattens, it causes your lungs to take in air, and when it releases, the air goes out. More About How it Works

 The right lung is slightly larger than the left.  Hairs in the nose help to clean the air we breathe as well as warming it.  The highest recorded "sneeze speed" is 165 km per hour.  The surface area of the lungs is roughly the same size as a tennis court.  The capillaries in the lungs would extend 1,600 kilometers if placed end to end. Facts About the Respiratory System

 We lose half a liter of water a day through breathing. This is the water vapor we see when we breathe onto a glass.  A person at rest usually breathes between 12 and 15 times a minute.  The breathing rate is faster in children and women than in men. More Facts About the Respiratory System

Take care of your respiratory system by taking deep breaths once in a while. You need to eat good foods to make your ribcage strong to protect the lungs and the heart. Those are some ways to take care of your respiratory system. How to Take Care of Your Respiratory System
