Answer:
When you breathe in, a muscle under your chest, called your diaphragm, moves down and your ribs move out. This makes the space bigger and so you get lower air pressure in your lungs. Air now rushes in from outside. When you breathe out your diaphragm moves up and your ribs move back in, and the air gets pushed out.
