Simple, fun and full

I has bought this book for my 5 year old daughter and it was really nice, well explained with shutters that reveal to us what he has in each layer ...
There is a page on the parts of the human body, a page on digestion, a page on breathing, the brain, the 5 senses and the disease / injury / recovery. Each page has a multitude of components and sub-components, so a lot of content. Frankly first encyclopedia on the popular human body. Everything is explained simply and playfully! My 2 large 8 and 10 years were also interested in the book and I think I could have bought for their age also because it is simple but complete for primary level. By cons, no explanation on the boy girl sex but for me, I bought a book on the subject so it does not bother me.
