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 has two lobes.

Tiny air sacs called alveoli and small tubes called bronchioles make up the inside of the lungs.
A thin membrane called the pleura covers the outside of each lung and lines the inside wall of the chest cavity. This creates a sac called the pleural cavity. The pleural cavity normally contains a small amount of fluid that… Read more about Non-Small Cell Lung Cancer
