The story
Quarky dives inside your chest to meet the tireless pump that sends blood to every corner of your body.
What you'll learn
- Your heart is a muscle about the size of your fist.
- It beats around 100,000 times every day, without a rest.
- Blood carries oxygen and food to every part of your body.
- Exercise makes your heart stronger, just like any muscle.
