How breathing works - Nirvair Kaur?

Breathing is like having a tiny fan inside your body that helps you stay alive and happy.

Every time you breathe in, air goes into your lungs through your nose or mouth, just like when you blow out birthday candles. Your lungs are like balloons, they fill up with air when you inhale. Then, when you breathe out, the air leaves your body, like when you puff out your cheeks after blowing a whistle.

How Your Body Does the Work

Your diaphragm, which is like a strong, stretchy muscle under your lungs, helps you breathe in and out. When it moves down, it gives your lungs more room to fill up with air, that’s inhalation. When it moves up, it pushes the air back out, that’s exhalation.

Your lungs are full of little tiny bags called alveoli, which are like mini balloons inside bigger balloons. These help your body get oxygen from the air and send carbon dioxide back out, kind of like a team of tiny helpers working together so you can play, run, and laugh all day long!
