God’s Wondrous Machine series
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

Understanding the mechanics of this system in transporting nutrients, blood, chemicals, and more to cells within the body is key to understanding how it helps fight disease as well as maintain a properly balanced temperature.
