🫀 In an average lifetime, the heart beats over 2.5 billion times and pumps about 1 million barrels of blood. 📚 Author Seymour Simon has written over 300 science books for children and has been called "the dean of children's science writing" by The New York Times. 🔬 The book uses actual photographs and medical imaging to show the inner workings of the heart, rather than relying on illustrations or diagrams. 💉 The smallest blood vessels in our bodies, capillaries, are so tiny that red blood cells must pass through them in single file. 🏆 Seymour Simon's work has won multiple awards, including the American Association for the Advancement of Science's Lifetime Achievement Award for his contribution to children's science literature.
