Question

Where is the air going when you breathe in using your stomach/diaphragm instead of your lungs/chest?

In: Biology

Answer 1

You always use your diaphragm to inhale!

But it is a hard muscle to visualize so we tell people to breathe like you’re trying to fill up your tummy first.

What you’re doing is making the pressure in your chest lower than the air outside so it rushes in. [I remember it being Bill, but fast forward to 09:55 to see a quick set up and visualization from an Episode of Bill Nye the Science Guy. ](https://youtu.be/aXkA5igrVSo)

To exhale your muscles push on your lungs making the pressure inside higher than outside making the air go out. Your lungs never get all of the air out without a trauma causing a “collapsed lung.”
