From the Publisher

Asking questions and discovering the how and why things work are often the starting points of any scientific inquiry. For children, many initial questions are often centered on the human body. Why do we eat? What organs help me breath? Why don't I have to tell my heart to beat, yet I tell my feet to move? This Lerner series presents information for intermediate readers to answer these questions and many others about systems of the body.
In Your Respiratory System, reader is invited to imagine sleeping and relaxing and realizes that breathing rates change as activity changes. How does it change when running? The body requires energy from oxygen to perform. More activity equates to more energy required and that translates to more oxygen needed throughout the body to complete the activity. What organs are part of the respiratory system? From the nose and throat, to the larynx and lungs, organs of the respiratory system are introduced. The structure and function of each organ and how it supports the entire system, enabling oxygen to be distributed throughout the body, is explored. Waste gases are expelled through the lungs, completing the cycle as air is inhaled and exhaled. Magnified pictures of the inside of the lungs, inflated alveoli, and tiny hair–like structures, cilia, in the bronchioles provide the reader with a point of reference as the inside of the human body is conceptualized.
Each book in the series focuses on one system as well as its interaction with other systems to keep the entire organism functioning. Photographs and diagrams appear as pages are turned to complement and pull the reader into the text. Questions are posed creating an interactive text that will delight!

The reader will learn that your breathing rate changes depending on your activity level, but they have probably observed that anyway. The oxygen you breathe is needed to burn the food you eat. Your respiratory system then moves the carbon dioxide that is produced from that food burning to your circulatory system. Excellent analogies such as "your nose is like the door to your respiratory system" are used. Mucus waits for dust and germs that enter your nose where you either cough it out or swallow it. There is a great photograph of the cilia that move the mucus around. You cannot breathe and swallow at the same time because of the flap that will close off either the tube to the stomach or lungs. These tubes are labeled later in the book. There are beautiful photos of the vocal cords next to the illustration of vocal cords open and closed. There are other photo and illustrations such as the alveoli and bronchi. This informative series is library bound, with a glossary and up to date websites, and would be welcomed in libraries and science teachers' rooms.
