(Family Features) The centerpiece of your respiratory system, your lungs have the important job of moving oxygen to your blood when you breathe in and removing carbon dioxide, a waste gas, when you breathe out.

Experts at the National Heart, Lung, and Blood Institute’s Learn More Breathe Better® program offer tips to help protect your lungs from injury or disease. Learn more at nhlbi.nih.gov/BreatheBetter.
