Dr. Mona Khanna: Our lungs are among the largest organs in our bodies. They are located on the right side and the left side of the heart and they are protected by our rib cage. They're responsible for keeping our cells and tissues alive by supplying them with fresh oxygen, which is delivered to the blood supply. What they do is they take a gas that your body needs to get rid of, that's called carbon dioxide and they exchange it for oxygen. The airways that bring air into the lungs are called the trachea and the bronchi and they are made up of smooth muscle and cartilage. This allows our airways to constrict and expand. Because the lungs are very moist though they can be an optimal breeding ground for bacteria that can lead to bronchitis or pneumonia.
