Question: How do your lungs work

Alex Pool answered on 13 Nov 2014:

Your lungs act a bit like two big balloons. Your muscles lift your rib cage up and a sheet of muscle just below your ribs down. That forces air to enter your lungs and you breathe in. They then push your rib cages down and the diaphragm goes back up to exhale.

In your lungs you have hundreds of blood vessels so that oxygen can pass from the air into your lungs and the waste carbon dioxide you’ve produced can go out of your blood and be exhaled.
