What is the Respiratory System?

The main organ in the respiratory system is your lungs. When you breath in your lungs are filled with rich oxygen, then when you breath out, you release the oxygenated air out to your surrounding. Other wise known as Carbon Dioxide, this happens because when you breath in, your heart pumps blood to the walls of your heart, then it absorbs the oxygen and it becomes carbon dioxide.

The respiratory system is when you to bring oxygen into your body, (breathing in) and remove the carbon dioxide from your body, (breathing out) because your body needs oxygen to survive. When your body uses the oxygen your cells produce carbon dioxide. Too much of carbon dioxide can kill you so that is why you get rid of the carbon dioxide (breathing in).

  • To help you breath
