The heart is a marvelous muscle. Readers can learn all about it: how it works, what happens when it doesn't work well, and how to keep the heart in good shape. Students are introduced to the parts of the heart, the function that the heart plays in carrying oxygen to every part of the body, and the role of white and red blood cells, capillaries, and more.
