Diaphragm

Real World Example

Imagine trying to inflate a balloon while holding it steady with one hand. Just as your hand keeps the balloon steady and controls how it inflates, the diaphragm plays a similar role in breathing by stabilizing and managing the expansion of your lungs. The diaphragm, like your hand with the balloon, acts as a muscle that manages the space and pressure below the lungs, allowing them to inflate and deflate smoothly with each breath.
