Sinopsis

Physiology, the study of the functions of organisms, comes in many forms—plant physiology, cell physiology, microbial physiology, and animal physiology, to name a few. This book focuses on human physiology, the study of how our bodies work. We emphasize normal physiology, but occasionally describe pathophysiology—what happens when normal body function is disrupted—to better demonstrate typical body function. For example, the effects of diabetes on body function are described throughout the book to illustrate the delicacy of body function and the interdependency of organ systems.

In this book, we take the systems approach to physiology; that is, we study one organ system at a time. An organ system is a collection of anatomical structures that work together to carry out a specific function. For example, the cardiovascular system functions to deliver oxygen- and nutrient-rich blood to the various organs

of the body. We will learn more about organ systems shortly. As we use the systems approach to studying physiology, you must remember that a single system cannot function alone. Thus a chapter on the urinary system will include some discussion of the cardiovascular system, because the two systems interact.

Because nearly everyone is curious about how the human body works, we hope that studying physiology will be one of your most satisfying academic experiences. You will also come to realize that physiology, like the other sciences, is not just a collection of well-worn facts but rather a work in progress. You will recognize that there are significant gaps in our understanding of how the body works, and you will see that much of our current understanding is subject to change as new discoveries are made.

Regardless of your background or current interests, your study of physiology will broaden your scientific outlook. You will begin to see the “big picture,” understanding body function not as a collection of unrelated phenomena but rather as a connected whole. You might even discover something else—that physiology is beautiful. Most of us who have decided to make it our life’s work think so.
