What do you think is the most amazing machine in the universe? A superconductor? The modern computer? A rocket ship? Think again: It's the human body! Astonishingly intricate and complex, your body grows, heals itself, and performs a mind-boggling number of complex functions all at the same time.

Inside Out Human Body takes you on an incredible journey through the powerful muscular system, the "bone zone" (aka the skeletal system), the long and windy road of the digestive system, the blood-pumping circulatory system, the forty-seven-mile long nervous system, and beyond.

Each section is fully illustrated with colorful diagrams and includes fun, interactive lessons for you to try yourself. You can learn how to take your own pulse, how to make your arms float, and even what the color of your urine means. Sometimes the most incredible wonders are right under our noses.

The Inside Out series also includes: Inside Out Pirate Ship, Inside Out Shark, Inside Out T-Rex, Inside Out Mummy, Inside Out Horse, and Inside Out Medieval Castle.
