How do our lungs work

Our lungs are incredible organs, and they are the centre of our entire respiratory system. The system is made up of the lungs, tissues, blood vessels, muscles of the chest, diaphragm and the trachea. Each part of the system is important to ensure the effective exchange of gases. It is your brain that controls the function of breathing which is the rate at which we breathe, whether this is fast or slow. The brain does this by detecting how well the body is bringing oxygen into the body and expelling carbon dioxide from the body.

As we inhale, the air that we breathe fills our lungs, and the oxygen from the air enters the bloodstream. As this happens, the carbon dioxide that we don’t need moves out of the bloodstream and into the lungs, where it is then exhaled.
