The reason for this is a protective measure in that if something happened to one, you have a back up to rely on. If one lung were to collapse because of a crush type injury, the other lung would have to work twice as hard to provide the same amount of oxygen to the body, but you would survive.

∙ 14y agoYou need to have two lungs because it balances your heart rate when you run or exercise your heart muscles. They work as a filter taking in Oxygen and spreading it to keep your body working at a steady rate. Imagine how hard it is to run 4 miles if you were running that much you are using it and need more air than you had before if u were walking and you could not catch your breath

Lungfish have 2 lungs but the Australian lungfish has 1.
The bronchial tubes connect the trachea and the lungs. Air moves through these tubes into and out of the lungs.
