How Your Body Works: What happens when your heart beats?

Product Description

The human body is like an amazing machine, constantly working to keep us fit and healthy. Each system in the body has a important job to do: your heart beats to pump blood around your body. It never stops beating so your blood never stops moving.
Find out what the heart looks like, what it does and what you can do to look after it.
Health checks, investigations and animal comparison panels offer further information.
Vibrant photographs show what the body looks like on the outside, biological diagrams show us what the body looks like on the inside.
