In this title, early fluent readers meet Riley, a girl who loves to swim and surf, as she learns about her respiratory system. Read along as Riley, her dad, and her doctor discuss how the mouth, nose, windpipe, bronchi, diaphragm, and lungs work together to help us breathe and transport oxygen throughout the human body. Vibrant illustrations and carefully leveled text engage young readers in a supportive educational fiction reading experience. Children can learn more about the respiratory system using Fact Surfer, our safe online search engine that provides relevant, age-appropriate websites. This book also features diagrams, a review section, tools for teachers and caregivers, a glossary, an index, and a table of contents. Grasshopper Books offers simple, fun fiction for emerging readers. Riley's Remarkable Respiratory System is part of Jump!'s Let's Look at Body Systems! series.
