Inside the Blood was a SUPER FASCINATING book about the blood system in the human body! I really enjoyed the overall look of the book and was not overwhelmed by the presentation. The book had many helpful diagrams and pictures to supplement the reading. I think this book could be read in sections or parts as a whole class with younger grades or as an independent read for upper grade levels. My favorite part of the book was the tiny blurbs with random blood facts, they lead me down many rabbit holes and I spent honestly 20 minutes in a conversation about blood. ( )
