The lungs are a pair of cone-shaped organs located in the chest that bring oxygen into the body and release carbon dioxide. Each lung is made up of lobes and surrounded by a membrane called the pleura. The diaphragm works with the lungs to allow breathing. The main function of the lungs is respiration, which is the process of inhaling oxygen and exhaling carbon dioxide through the respiratory airways and into the lungs. Common lung diseases include pneumonia, tuberculosis, lung cancer, and emphysema.
