Your Heart
A muscle the size of your fist that pumps blood all around you — about 100,000 times a day! Put your hand on your chest and feel it go.
All about you
👋 The Body Machine
Your body is made of tiny building blocks called cells — trillions of them! They team up to make your organs (like your heart and brain), your muscles, and your bones. Every single second, your body is busy beating your heart, breathing air, and thinking thoughts — all without you even asking it to! 🤯
Meet the parts
🫀 Inside You
🧠
Your Brain
The boss of your body! It helps you think, remember, move, and dream. It never takes a day off.
🦴
Your Bones
You have 206 bones holding you up like a frame. Babies are born with even more — some join together as you grow!
🫁
Your Lungs
Two stretchy balloons that fill with air when you breathe in and let it out when you breathe out. Take a deep one!
💪
Your Muscles
Over 600 of them help you run, jump, smile, and wiggle. Your tongue is a muscle too!
🩸
Your Blood
It carries food and air to every part of you, like tiny delivery trucks zooming through your veins.
