The third book in the popular elementary anatomy series, God's Wondrous Machine, focuses on the heart, blood, and the blood vessels that make up the body's circulatory system.


With loads of awesome imagery, Dr. Callentine shows kids (and parents) the mechanics of this system in transporting nutrients, blood, chemicals, and more to cells within the body. All this is the key to understanding how it helps fight disease as well as maintain a balanced temperature. This full-color book delights in sharing the truth with children of how they are wonderfully made!

Developed by a pediatrician, this book focuses on the amazing design and functionality of the human body’s circulatory system. You will discover amazing facts like:

  • The human heart beats 100,000 times a day, and one drop of blood has 5 million red blood cells in it
  • A timeline of important discoveries and innovators as well as key anatomical terms and concepts
  • Discussions of disease and proper care for optimal health!
