Human Physiology 7th edition focuses on the mechanisms of body function from cells to systems and is organized around the central theme of homeostasis
I have been teaching physiology since the mid-1960s and remain awestruck at the miraculous intricacies and effi ciency of body function. No machine can perform even a portion of natural body function as eff ectively. My goal in writing physiology textbooks is not only to help students learn about how the body works but also to share my enthusiasm for the subject matter. Most of us, even infants, have a natural curiosity about how our bodies work. When a baby fi rst discovers it can control
its own hands, it is fascinated and spends many hours manipulating them in front of its face. By capitalizing on students’ natural curiosity about themselves, I try to make physiology a subject they can enjoy learning.
Even the most tantalizing subject can be diffi cult to comprehend if not eff ectively presented, however. Th erefore, this Human Physiology 7th has a logical, understandable format with an emphasis on how each concept is an integral part of the entire subject. Too often, students view the components of a physiology course as isolated entities; by understanding how each component depends on the others, a student can appreciate the integrated functioning of the human body. The text focuses on the mechanisms of body function from cells to systems and is organized around the central theme of homeostasis—how the body meets changing demands while maintaining the internal constancy necessary for all cells and organs to function.
This text is written with undergraduate students preparing for health-related careers in mind. Its approach and depth are appropriate for other undergraduates as well. Because it is intended as an introduction and, for most students, may be their only exposure to a formal physiology text, all aspects of physiology receive broad coverage, yet depth, where needed, is not sacrifi ced. Th e scope of this text has been limited by judicious selection of pertinent content that a student can reasonably be expected to assimilate in a one-semester physiology course. Materials were selected for inclusion on a “need-to-know” basis, so the Human Physiology 7th is not cluttered with unnecessary detail. Instead, content is restricted to relevant information needed to understand basic physiologic concepts and to serve as a foundation for future careers in the health professions.
