Open this book to visit a fascinating and astonishing place—the human body.

Your tour begins with the trillions of cells that make up the body.

Did you know? Our bodies are made up of over 30 trillion cells.

Travel through the senses of sight, hearing, taste, and smell. Tour the mouth and teeth, then down into the stomach and intestines, and on to the bones, lungs, heart, and blood.

Did you know? Newborn babies have more bones than adult humans do.

Along the way, amazing numbers and fascinating facts will help you explore and understand the workings of the body all humans share. If you want to learn more, make a bonus stop in the back of the book for information, resources, and fun hands-on activities.

So come one, come all ... on a Number Tour for Curious Kids!
