Hear Your Heart

Illustrated by Holly Keller.

While you're awake . . . while you're asleep . . . your heart is always beating. You can listen to your heart. You can feel it beat. But just how does your heart work? Paul Showers and Holly Keller introduce readers to human anatomy in this clear and accessible look at the circulatory system. A page of activities and further resources gives young biologists more information on keeping their hearts healthy and strong.
