11 Nonfiction Books That Explain The Mysteries Of The Human Body — Like WTF Is Kissing All About?

Every single one of you has a human body that is fascinating, wondrous, and surprising in many ways. If you are curious about how your body actually functions and keeps you alive each and every day, you might want to read a few scientific books about the human body.

Every part of your body tells its own story — the beating of your heart, the rumble of your stomach, the flexing of your fingers. No matter what you're doing, at any given point in time, your body is doing millions of things: breathing, digesting, pumping blood, creating proteins, releasing hormones, and on and on and on. Scientists and doctors have spent millennia exploring all the different ways our bodies function, and answering that unending question of why it does the things that it does.

But you don't have to be a scientist to be intrigued by the way the human body works. After all, it's literally who you are, and there is so much to explore. From the top of your head to the tips of your toes, here are 11 books that will teach you loads about the human body and open your eyes to how miraculous it truly is:
