Letting the air fill your lungs from a balloon
Letting the air fill your lungs from a balloon
I blow a balloon full with air.
If I then inhaled it back in and let it flow back in my lungs, all at once, would the amount all go in the lungs and destroy them (since not all the air could possibly fit in)?

Maybe not a balloon, but air expansion can cause injuries in scuba divers if they hold their breath when surfacing quickly from a depth.
Yeah, I've heard of that too.
In this example however, both blowing the balloon and taking the air in would happen in the same room, under same conditions (temperature and air pressure).
