Overview

Take a deep breath and then let it out. Did you feel your chest rise and fall? That is actually your lungs filling with oxygen and then pushing carbon dioxide back out when you exhale. Without your lungs and your entire respiratory system, the rest of your body wouldn't receive the oxygen you need to survive. To give your body the oxygen it needs, you breathe twenty times every minute. You breathe more than twenty thousand times each and every day. Acclaimed science writer Seymour Simon explores the important journey that air takes in and out of your lungs.

Editorial Reviews

Children's Literature - Judy Podlesney
Instructions to take a deep breath and time how long you can hold it introduces the reader to an adventure through the respiratory system. We may be able to go without food for days, but we can only go for a minute or two before needing to take a breath. Oxygen is needed for many bodily functions as well as for breathing. Our respiratory system helps us to speak, blow balloons, and play a trumpet. The author takes us on a journey that begins with air entering the nose, traveling through the nasal cavity, sinuses, pharynx, larynx, trachea, bronchi, and ending at the alveolar sacs, where oxygen and carbon dioxide are exchanged. Along the way the role of each structure is explained clearly with interesting facts, such as: in the nasal cavity, the tiny olfactory cells numbering fifty million in humans (and two billion in dogs) can distinguish about ten thousand different odors. In addition to details of respiration we learn about coughing, sneezing, hiccups, and respiratory illnesses. Across from the easy-to-read text on each page are colorful and dramatic drawings or photos. A high-speed photo of a man sneezing is a graphic tool for teaching the importance of covering the mouth. Significant words in the text are highlighted and explained in a glossary. Part of a series with the "Smithsonian Institution," the book is a helpful addition to a curriculum on learning about the body.
