Bones Book/Book and Skeleton

MAKE NO BONES ABOUT ITDiscover how the tiniest bones let you hear music, where a bite of apple goes once you swallow it, and why you shrink during the day and grow again at night.This lively guide tells how bones grow, fit, fuse, and sometimes break. It explains how the bones make blood, and why we start with over 800 bones and end up with 206 when we finish growing. Plus all about the heart, our strongest muscle; the brain, which accounts for 2% of our weight but saps 20% of our energy; and the lungs whose several hundred million air sacs fill up and empty 15,000 times a day.Filled with projects, THE BONES BOOK is also the aspiring anatomist's companion to the 25-piece custom-molded skeleton included in the package.Cumbaa, Stephen is the author of 'Bones Book/Book and Skeleton' with ISBN 9780894808609 and ISBN 0894808605.
