How do we breathe and why do we need oxygen? Your lungs work hard to keep oxygen flowing through your blood. This book explains how the respiratory system functions to take in the air we need to live.
These books take difficult concepts and explain them clearly and concisely. Each title provides enough detail for a basic understanding of the topic and begins with an overview, “What Is the...?” Other chapters explore the parts of the system (e.g., joints, the heart), and ways to keep it healthy. “Fun Facts” present “wow” information that readers will want to share. The color illustrations often combine photographs of children with diagrams and detailed lifelike pictures of the body system. These titles have more detail than those in the “My Body” series.
