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.
The lungs are one of the body's vital organs. The lungs are located inside the chest cavity, just behind the breastbones. They are responsible for the transfer of oxygen to the body and work in conjunction with other individual organs and bodily systems to ensure gas exchange takes place.he heart is the major organ in the circulatory system, and the lungs and heart are always in cooperation. The heart passes used blood, rich in carbon dioxide, back into the lungs. The carbon dioxide passes into the alveoli of the lungs and is released when we breathe.
