Packed with photographs, computer-generated artwork, cut-aways and diagrams, this book on the human body will educate, fascinate and improve understanding of our miraculous bodies. From breathing to blood and muscles to metabolism, this book takes a look inside the human body, explaining how it works, how to keep it working and what may go wrong with it. It also asks questions that concern young readers and the choices they face in terms of their own bodies, regarding drug use, contraception and smoking.
