Join award-winning science writer Seymour Simon as he investigates one of the body's most important organs: the heart.

Acclaimed science writer Seymour Simon brings you this indispensable guide that takes you through the heart, from atrium to capillary and back again.

By the time you finish reading these words, your heart may have beaten up to 50 times.

You may not be able to see your own heart, but all you have to do is look inside this book to see how this amazing organ works.
