Inside the Human Body

What is the most complex machine on earth? The human body! With Inside the Human Body, readers ages 12 to 15 peel back the layers to take a look inside this amazing machine and learn basic anatomy—bones, muscles, blood vessels, nerves, and organs. We also explore the body’s physiology and how its organs work together to allow us to function and survive. Take a ride through the different organ systems, including the musculoskeletal system, cardiovascular system, respiratory system, nervous system, endocrine system, digestive system, immune system, and urinary system, and investigate each system’s role in operating our human body machine. Science-minded STEM activities, text-to-world connections, essential questions, and links to online resources engage readers far beyond the page.
