I absolutely love this book! I bought it for my 10 year old who loves biology and science, and loves to learn how things work. We read through the chapters together, and there is a ton of fantastic information and fun little facts about the entire human body in this book! Even I learned information and fun facts that I did not know! The illustrations beautifully complement the text as well! I absolutely, 100% recommend this book for anyone, child or adult, who wants to learn more about the human body and it’s functions!
