The human body is complicated and incredible! The many parts of the body form a network of systems that work together to keep you alive and active.

Each chapter focuses on a different system: outer body, nervous system, skeleton and muscles, breathing system, heart and blood, digestive system, urinary system, growing and changing. Body maps are included to show how organs and systems all function together. The mechanics of the human body are described in concise and easy-to understand text while infographics and photographs bring the various systems to life.
