Each book gives an excellent breakdown and description of all of the body parts, organs, and fluids that are involved in that particular system and how everything ties together. These titles explain the body systems in a way that kids can understand and tie in to aspects of their own lives. Full-color and thorough illustrations complement the clearly presented biology of the human body. A focus on health and wellness rounds off the package. Titles include chapter notes, a further reading list, for more information, Internet addresses, a glossary, and an index.
