Human Body Detectives Merrin and Pearl are at it again. Their magical ability to jump into people's bodies and explore their systems (digestive, immune, circulatory, skeletal, nervous systems) combines science with their fun adventures to help kids understand how their anatomy, physiology, and how to nourish it well.

In A Heart Pumping Adventure, Merrin and Pearl enter their dad's circulatory system to explore how healthy his heart is after they see him overindulging in a not-so-healthy breakfast. During their journey, they ride on a red blood cell through the lungs, get lodged and stuck in a blood vessel, deliver oxygen to the body, and so much more. In the end, they not only learn about what foods their dad should eat to keep his heart working well, but they also get a firsthand lesson on the functions of the circulatory system.

A Heart Pumping Adventure is one of five stories featured in the Human Body Detectives series, along with, The Lucky Escape, Battle with the Bugs, Osteoblasts to the Rescue, and Brainiacs.

The Human Body Detectives series explores science with a twist-an accessible lesson about the human body presented in a fun, relatable way that kids will love. Each Human Body Detective book can stand alone or be read as part of the series.

Ideal for both the home and the classroom, these beautifully illustrated books offer activity pages as well as a glossary of terms and information about the best foods kids can eat to keep their bodies healthy. A curriculum for teachers and homeschooling families is also available for each book on the Human Body Detectives website.
