This is a great introduction to how the human body works. My five year old has become interested in the subject and I found it to be a great beginner book for her.
Excellent introduction to body systems, written for early independent readers (2nd grade). Clear information, good diagrams, love the fact that photos of diverse kids are used throughout.
