Hall, Ph. Arthur C. Guyton almost 55 years ago. His main goal with each issue was to instruct students in physiology, not to impress his professional colleagues. Arthur C. I had the privilege of working closely with Dr. Guyton for almost 30 years and the honor of helping him with the ninth and tenth editions. For the eleventh edition, I have the same goal as in previous editions: to explain, in language easily understood by students, how the different cells, tissues, and organs of the human body work together to sustain life.

This task has been challenging and exciting because our growing knowledge of physiology continues to unravel new mysteries of bodily functions. Many new techniques have been developed for learning about molecular and cellular physiology. We can increasingly present the principles of physiology in the terminology of the physical and molecular sciences rather than simply in a series of separate and inexplicable biological phenomena. This change is welcome, but it also makes reviewing each chapter a must, grasp a need.

In this edition, I have tried to maintain the same unified organization of the text that has been helpful to students in the past and to ensure that the book is comprehensive enough that students wish to use it in later life as a basis for their professional studies careers. I hope this textbook conveys the majesty of the human body and its many functions and encourages students to study physiology throughout their careers.

Physiology is the link between basic science and medicine. The great beauty of physiology is that it integrates the individual functions of all the different cells, tissues, and organs of the body into one functional whole, the human body. In fact, the human body is much more than the sum of its parts, and life is based on this total function, not just the function of individual parts of the body isolated from each other. This brings us to an important question: How do the separate organs and systems coordinate to keep the entire body functioning properly?

Fortunately, our bodies are endowed with a vast network of feedback controls that strike the necessary balances without which we could not live. Sensations of cold make us look for warmth. Other forces cause us to seek fellowship and to reproduce. Thus, the human being is actually an automaton, and the fact that we are sensing, feeling, and knowledgeable beings is part of this automatic sequence of life; these special attributes allow us to exist under widely varying conditions.

The basic living unit of the body is the cell. Each organ is an aggregate of many different cells held together by intercellular supporting structures. Each type of cell is specially adapted to perform one or a few particular functions. For instance, the red blood cells, numbering 25 trillion in each human being, transport oxygen from the lungs to the tissues. Although the red cells are the most abundant of any single type of cell in the body, there are about 75 trillion additional cells of other types that perform functions different from those of the red cell.

The entire body, then, contains about trillion cells. Although the many cells of the body often differ markedly from one another, all of them have certain basic characteristics that are alike. For instance, in all cells, oxygen reacts with carbohydrates, fat, and protein to release the energy required for cell function.

Further, the general chemical mechanisms for changing nutrients into energy are basically the same in all cells, and all cells deliver end products of their chemical reactions into the surrounding fluids. Almost all cells also have the ability to reproduce additional cells of their own kind.

Fortunately, when cells of a particular type are destroyed from one cause or another, the remaining cells of this type usually generate new cells until the supply is replenished.

About 60 percent of the adult human body is fluid, mainly a water solution of ions and other substances. Unlike other textbooks on this topic, this clear and comprehensive guide has a consistent, single-author voice and focuses on the content most relevant to clinical.

Known for its clear presentation style, single-author voice, and focus on content most relevant to clinical and pre-clinical students, Guyton and Hall Textbook of Medical Physiology, 14th Edition, employs a distinctive format to ensure maximum learning and retention of complex concepts.

A larger font size emphasizes core information, while supporting information, including clinical examples, are detailed in smaller font and highlighted in pale blue — making it easy to quickly skim the essential text or pursue more in-depth study. This two-tone approach, along with other outstanding features, makes this bestselling text a favorite of students worldwide.
