The lung is an organ found in your chest cavity. Each lung is divided into lobes. On the left side, you have the left upper- and the left lower- lobe. On the right side, there are 3 lobes: the right upper-, mid-, and lower lobe. A thin lining, called the pleura, surrounds the lobes of the lung. As you breathe, air moves down your windpipe (your trachea), through a tree-like structure called the bronchi.
