Skin, Cells at Work
by Ralph Mitchell

This National Geographic Theme Set book describes the system and work of skin cells in our bodies. It explains that skin cells are cells in the body that help it live, heal wounds, and grow, and they form a layer to protect the body and keep the body's temperature normal. Excellent photography, illustrations, and diagrams help the understanding of the well-written text.
