Take a deep breath and then let it out.
Acclaimed science writer Seymour Simon explores the important journey that air takes in and out of your lungs..
You breathe more than twenty thousand times each and every day.
To give your body the oxygen it needs, you breathe twenty times every minute.
Without your lungs and your entire Respiratory system, the rest of your body wouldn\'t receive the oxygen you need to survive.
Did you feel your chest rise and fall? That is actually your lungs filling with oxygen and then pushing carbon dioxide back out when you exhale.
