In this volume, our heroes Geo and Dr. Brain face hostile white blood cells, Phoebe's powerful heartbeat, and a bruise that threatens to suck them out of the bloodstream and leave them stranded forever! As you follow their fast-paced comic adventure through Phoebe's blood, heart, and lungs, you'll learn all about the human circulatory system. Have you ever wondered...-How your heartbeat keeps a steady pace?-Why your blood forms a scab after you get a cut or scrape?-How your body defends itself against bacteria and other intruders?-How children inherit their blood types from their parents?-How your muscles and brain get the oxygen and nutrients they need to survive?-How the body filters out toxins in food before they reach your bloodstream? For ages 8+ Translated by Army Chung
