The lungs are a pair of cone-shaped breathing organs in the chest. The lungs bring oxygen into the body as you breathe in. They release carbon dioxide, a waste product of the body's cells, as you breathe out.
Each lung has sections called lobes. The left lung have two lobes. The right lung is slightly larger and has three lobes.
Two tubes called bronchi lead from the trachea (windpipe) to the right and left lungs.
