where is your lung
What Are the Lungs? Your lungs are organs in your chest that allow your body to take in oxygen from the air. They also help remove carbon dioxide (a waste gas that can be toxic) from your body. The lungs' intake of oxygen and removal of carbon dioxide is called gas exchange. Gas exchange is part of breathing. Breathing is a vital function of life; it helps your body work properly. Other organs and tissues also help make breathing possible.
