What begins as a camp fishing trip becomes a fascinating lesson in the heart and circulatory system when the kids ask the camp doctor for a "heart-to-heart" talk. Where does blood come from? What are cells? Why are veins red and arteries blue? How does the heart pump blood throughout the body? If someone in your family has heart disease, can you catch it? Learn all about the heart, how it works, and how to keep it healthy in this breezy yet fact-filled book, packed with charming and accurate illustrations of this mysterious aspect of the human body. Then, enjoy the big surprise when the discussion winds up in the doctor's library.
