Every part of your body needs oxygen from the air you breathe in order to survive. The delicate structure of the lungs performs the complex tasks of breathing and transferring oxygen to the rest of the body. At the same time, it helps protect the body from outside attack. Most of the time we are not even aware that our lungs are working, but they can be damaged in many ways and become less efficient at taking oxygen from the air and getting rid of waste carbon dioxide.

Every day we breathe about 22,000 times. Our breath, and our lungs, are incredibly fundamental to the functioning human body. Breathing is after all, a symbol of life.
