Parts of the Body [EPUB ebook] 

This is an introduction to human anatomy and physiology written for children ages 4 and older. The book teaches the major organ systems of the body in the simplest terms, making the material accessible to young children. Written by a family physician with young children of his own, this book is part of a nonprofit program to deliver free books to farmworker families in the Salinas Valley. Illustrations and diagrams show how the organ systems function in a way that’s easy to understand and can unlock your child’s inner scientist or doctor.
