An organ is a body part with a special job. Your brain thinks, your heart pumps, your lungs breathe. Tap each one to find out what it does.
Pick one from the list to learn its job.
Your heart is a muscle the size of your fist. It pumps blood all around your body — about 100,000 times a day! When you run and play, it beats faster to give your muscles more oxygen. Press the button and watch.
1. Why does your heart beat faster when you run? Your muscles need more oxygen, so the heart pumps blood faster to deliver it.
2. Your skeleton has about how many bones? And name one job it does. About 206 bones — they hold you up and protect soft parts (like the skull protects the brain).
3. Put the journey of food in order: stomach, mouth, teeth. Mouth → teeth chew it → stomach breaks it down. Then the body takes the goodness out.
4. Which organ is the "boss" that sends messages to all the others? The brain — it controls everything, even your heartbeat and breathing.
No organ works alone. Your lungs grab oxygen, your heart pumps it in your blood, your muscles use it to move, and your brain tells them all what to do. Look after the team — good food, water, sleep and exercise — and it looks after you.
