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.
This is way too graphic for my tastes. The whole series is. If you cringe at medical shows, this series is definately not for you or your kids. However, if you don't mind real pictures of real bodies sliced and diced, it is a really good book. My daughter (who LOVED "Bodies: The Exhibit") has turned this into a favorite bedtime book. Yuck!
