The Respiratory System
And everything about it....
What is it???
Each day we breathe about 20,000 times. All of this breathing couldn't happen without help from the respiratory system, which includes the nose, throat, voice box, windpipe, and lungs. With each breath, you take in air through your nostrils and mouth, and your lungs fill up and empty out. As air is inhaled, the mucous membranes of the nose and mouth warm and humidify the air.
-kids health.orgThe Respiratory System separates oxygen from other gasses in the air. The circulatory system does this in 3 simple steps.
1. Acquire oxygen from the air.
2. Transport it to the lungs.
3. Separate oxygen from the rest of the air.
4. Send the carbon dioxide back out.
