Can Your Heart Stop Pumping?

We've learned a lot about your heart, the incredible muscle that works hard inside your chest every second of every day. But what about when you're resting or even sleeping?

Does your heart ever just take a break and stop pumping completely?

Your heart is like a secret engine inside you. It never stops, even when you're sleeping! But what does it actually do all day long?

Your Heart's Job

Your heart's main job is to push blood around your body. Think of blood like tiny delivery trucks carrying good stuff to all your body parts. It brings fuel and takes away trash!

It's a Muscle!

Your heart is a special muscle. It's about the size of your fist. Make a fist! That's how big your heart is!
