Principles of Anatomy and Physiology, the market leading text through many editions, owes its success to its accurate and authoritative presentation of the principles of the human structure and function. Equally important has been the pioneering and continually evolving efforts of the authors to develop an outstanding illustration program and innovative pedagogical features that promote understanding. The product of years of teaching experience, this text provides a superb balance between anatomy and physiology while emphasizing correlations between normal physiology and pathophysiology, normal anatomy and pathology, and homeostasis and homeostatic imbalances. This text has been, and continues to be, the standard upon which all other texts are mirrored and compared.
