The lungs provide a place where oxygen can reach the blood and carbon dioxide can be removed from it. Each of your body systems relies on the others to work well. Your respiratory system relies on your circulatory system to deliver the oxygen it gathers, while the muscles of your heart cannot function without the oxygen they receive from your lungs. ...
