Great Question: And I have a better answer: unlike the american bison, most mammals have two separate pleural or lung cavities. If one lung collapses, the problem does not usually affect the other side. This is why bison were easy to hunt. If you hit one side of the chest, both lungs could collapse. The picture shows human anatomy, wish i could also post a bison picture as they are majestic creatures.
