Ages 7 to 10, Grades 2 to 5
  

Did you know that the number of microorganisms in your body outnumber your own cells by 10 to 1? Or that every second, your body produces around 25 million new cells? Or that a human being has fewer chromosomes than, wait for it… a pineapple!

30 Trillion Cells provides a detailed look at the topic of the human body, covering of the body's major systems and organs, as well as looking at the cellular level and at the genetics that play a part in making us who we are. Readers will also explore the human body as a microbiome, discovering the trillions of 'good' microbes that live on and within us, doing their bit to keep us healthy. Features expansive, artistic illustration that is as beautiful to look at as it is educational.
