The lungs are the organs in your chest that help you breathe. They are shaped like cones and come in a pair. Each lung has sections called lobes. The left lung has 2 lobes. The right lung is a little bigger than the left lung. It has 3 lobes. When you breathe, air goes into your mouth and down your windpipe, called the trachea. The trachea then divides into 2 tubes, called bronchi. One tube goes to each lung.
