Photography of anatomical models and microscopic views, along with clear diagrams and historical artworks, offer a view of the discoveries that have changed our understanding of the human body. See how leeches were used by medieval doctors; what a human cell contains; how X-rays work; how muscles help us to move; why we have fingerprints; what is inside our bones; how food is digested; why we are able to talk. Learn how the skeleton is put together; why blood is red; what each part of the brain controls; how acupuncture works; what makes us yawn; how the body reacts to seal a wound; why our noses run when we cry; how hairs help us to smell. Discover how scientists first studied anatomy; why we sweat; how our lungs could cover the area of a tennis court; what causes diabetes; how the heart beats; why ears 'pop'; how babies grow in the womb; what gives us a sense of touch; how we see.
