A truly extraordinary interactive look at the miracle of the human body. Designed to take the reader on a fascinating step-by-step journey of discovery, each spread focuses on a part of the body. It provides a visually rich and clearly described explanation of the vital processes, such as circulation, the nervous system, and the organs. Uniquely, a pocket in each spread also provides the component parts to construct the appropriate section of a detailed model of the human skeleton with internal organs in place. This original and superbly engineered book offers the whole family a great way to understand how our bodies work.
