Well, it depends on your size and sex as well as lung capacity. Lung size is generally assessed by total lung capacity (TLC) or vital capacity (VC). Your lungs make up one of the largest organs in your body, and they work with your respiratory system to allow you to take in fresh air, get rid of stale air, and even talk. Your lungs are in your chest, and they are so large that they take up most of the space in there. You have two lungs, but they aren't the same size the way your eyes or nostrils are. Instead, the lung on the left side of your body is a bit smaller than the lung on the right. This extra space on the left leaves room for your heart. Most of the chest volume (thoracic cage) is occupied by the lungs. Think of a short man and compare his chest volume to that of a fullback football player. The football player will have larger lungs than the short man (or woman). http://encarta.msn.com/media_461516290_761570316_-1_1/Human_Lungs.html http://www.ask.com/web?q=human%20lungs&o= ... more
