A thorough introductory text on human form and function, this text presents a large, complex body of scientific knowledge in an easily understood, conversational writing style. Focusing on concepts rather than descriptions, the text uses a 'big picture' theme of body function and also explains the body's homeostatic regulation. For the first time, every new textbook includes a downloadable e-book, which is a fully searchable, electronic version of the text plus learning resources from Anatomy & Physiology Online - with animations by body system, images, an electronic colouring book, interactive exercises, and more.
