How Breathing Works?

Breathing is how your body gets air to help you move and stay alive.

When you breathe in, air goes into your lungs through your nose or mouth. It's like when you blow out birthday candles, except instead of blowing out, you're taking air in. This air has a special gas called oxygen, which is like food for your body’s tiny workers (your cells).

Your lungs are like big balloons inside your chest. When you breathe in, these balloons fill up with air, and when you breathe out, they let the air go back out. This happens because of your diaphragm, a strong muscle under your ribs that goes up and down like a see-saw.

Once the air is inside your lungs, the oxygen moves into your blood, it's like a tiny boat ride! Then your blood takes this oxygen all around your body, so you can run, jump, laugh, or even sleep. When you breathe out, your body sends back carbon dioxide, a gas that helps your body keep working smoothly.

You do this without thinking, just like how you don’t think about walking when you take a step!
