Your body needs extra oxygen when it’s working really hard and wants more energy to keep going.
Imagine you’re running as fast as you can to catch your favorite ice cream truck. Your legs are moving super quick, your heart is beating like a drum, and your lungs are puffing out big breaths, that's because your body needs extra oxygen to make more power for all that running!
How the Body Uses Oxygen
When you're just sitting quietly, your body uses oxygen slowly. It’s like a little fire burning in the background. But when you run or play, it’s like lighting a big bonfire, your body needs extra oxygen to keep that fire going strong.
Your lungs take in more air, and your blood carries that extra oxygen to your muscles. That helps them work harder and longer, so you can keep running until you get that ice cream!
So next time you're out of breath after a game, remember, your body is just asking for extra oxygen to power through!
