It is integrative and encompasses everything from the study of molecules and subcellular components to the study of organ systems and their interactions that allow us to function as living beings. Because human physiology is a rapidly expanding discipline and covers a broad scope, the vast amount of information potentially applicable to the practice of medicine can be overwhelming. Therefore, one of our goals for writing this “Pocket Companion” was to distill this enormous amount of information into a book that would be small enough to be carried in a coat pocket and used often but still contain the basic physiologic principles necessary for the study of medicine. The pocket companion was designed to accompany Guyton and Hall’s Textbook of Medical Physiology, 12th Edition, and it cannot serve as a substitute for the parent text. Rather, it is intended to serve as a concise overview of the most important facts and concepts from the parent text, presented in a manner that facilitates rapid comprehension of basic physiologic principles. Some of the most important features of the pocket companion are as follows: • It has been designed to serve as a guide for students who wish to review a large volume of material from the parent text rapidly and efficiently. The headings of the sections state succinctly the primary concepts in the accompanying paragraphs. Thus the student can quickly review many of the main concepts in the textbook by first studying the paragraph headings. • The table of contents matches that of the parent text, and each topic has been cross- referenced with specific page numbers from the parent text. The pocket companion has been updated in parallel with the Textbook of Medical Physiology. • The size of the book has been restricted so it can fit conveniently in a coat pocket as an immediate source of information when needed. Although the pocket companion contains the most important facts necessary for studying physiology, it does not contain the details that enrich the physiologic concepts or the clinical examples of abnormal physiology that are contained in the parent book. We therefore recommend that the pocket companion be used in conjunction with the Textbook of Medical Physiology, 12th Edition. I am grateful to each of the contributors for their careful work on this book. Contributing authors were selected for their knowledge of physiology and their ability to present information effectively to students. We have strived to make this book as accurate as possible and hope that it will be valuable for your study of physiology. Your comments and suggestions for ways to improve the Pocket Companion are always greatly appreciated. John E.
