ng resource, David Macaulay reveals the inner workings of the human body as only he could. In order to present this complicated subject in an accurate and entertaining way, he put in years of research. He sat in on anatomy classes, dissections, and even reached inside the rib cages of two cadavers to compare their spleen sizes. He observed numerous surgeries, including a ten-hour procedure where a diseased pancreas was removed, as well as one where a worn-out old knee was replaced by a brand new one. This hands-on investigation gives Macaulay a unique perspective to lead his readers on a visual journey through the workings of the human body.

The seven sections within the book take us from the cells that form our foundation to the individual systems they build. Each beautifully illustrated spread details different aspects of our complex structure, explaining the function of each and offering up-close glimpses, unique cross-sections and perspectives, and even a little humor along the way.
This one-of-a-kind book can serve as a reference for children, families, teachers, and anyone who has questions about how his or her body works. When readers see how David Macaulay builds a body and explains the way it works, they will come away with a new appreciation of the amazing world inside them.
