This is a classic Usborne book which has been enjoyed by three generations since its first publication in 1975 - now completely reillustrated by the original artist Colin King, to celebrate the 40th anniversary of Usborne Publishing. Anyone who remembers this book from their own childhood will love to introduce a new generation to this unique visual explanation of how the human body works. Those previously unfamiliar with it are in for a treat. It covers all the basics of human biology.
