Vander's Human Physiology is an integrated package of textual and digital material that delivers basic and clinical content, real-life applications, and educational technologies. All these pieces come together to facilitate learning and enthusiasm for understanding the mechanisms of body function. Key focus areas include homeostasis, exercise, and human health. These and other areas of interest are elaborated upon, beginning with Chapter 1, where the key 'General Principles of Physiology,' an underlying theme in the book, is first introduced. Unifying themes, such as homeostasis, are explored throughout the book at all levels of system, organ, tissue, and cellular function- themes that are always related to pathophysiology through the use of compelling clinical case studies in all chapters, and a final chapter with several cases that integrate material across the entire book.
