Some Fascinating Facts*
- People who have a large lung capacity can send oxygen around their bodies faster. You can increase your lung capacity with regular exercise.
- Lungs contain approximately 2,400 kilometers of airways and 300 to 500 million air sacs (alveoli).
- Your left and right lungs aren’t exactly the same. The lung on the left side of your body is divided into two lobes. The lung on your right side is divided into three. The left lung is also slightly smaller, allowing room for your heart.
