Vivid color photos and artwork are enhanced with gatefolds, tabs to lift, and ingenious pop-up features that give kids an interactive tour of the human body. This book's illustrations and explanatory text demonstrate how food nourishes the body, how the network of bones gives the body both strength and flexibility, how the brain controls everything we think and feel, and much more. Interactive features on every two-page spread include: Overlaying flaps showing major body systems A pop-up skeleton A pop-up heart with flaps that reveal its structure A wheel to turn, showing how the eye's iris dilates and contracts according to the amount of available light . . . and many others Here's a fine introduction to the science of physiology for young readers, a book that shows how the human body's many organs work together, making us more dexterous than any robot, and able to perform tasks beyond the capabilities of even the most advanced machines. - from Amzon
