"Did you know that if you spend one hour reading this book, you'll move your eye muscles about 10,000 times? During that hour you'll also breathe air, hear sounds, and digest food, while your hair grows and your skin cells regenerate. Your neurons may even make a few new connections as you learn from what you read! In Body Systems, you can find out all about the systems of the human body and how they are constantly at work to keep you healthy, keep you growing, and make you who you are."--Provided by publisher
