We breath the through the lungs. The air goes in and out of our lungs. So why is it that most of the time it’s our stomach that inflates rather than the chest?

Answer 1

Have you ever chewed gum and blew a bubble in reverse? Or in other words sucked in so a bubble formed in your mouth (allows for some awesome loud snaps). That’s essentially what’s happening in your stomach. A big muscle called your diaphragm with the assistance of other muscles expands the space your lungs can fill into( which is similar to you inhaling to reverse the gum bubble). This creates a vacuum to suck air into your lungs.
