Without bones, the human body couldn't stand on its own. Without muscles, we couldn't move! These important systems are highlighted together in this book, similar to how they work together in the body. Readers take a tour of the skeletal and muscular systems, complete with simple diagrams, as they learn what each part does. In addition, they learn how to care for these systems and why it is important to overall health. Including everything from what foods fuel growth and keep bones strong to joyful movement, this book is a great companion to any physical education, health, or science classroom learning.
