Ganong's Review of Medical Physiology, 26th Edition (Twenty-Sixth Edition)

Ganong's Review of Medical Physiology by Kim E. Barrett and Susan M. Barman is a systems-based physiology text used by medical students, graduate students, and clinicians reviewing the physiologic mechanisms underlying human health and disease.

Medical physiology forms the mechanistic foundation for understanding pathophysiology, pharmacology, and clinical medicine. This text works through each organ system's normal function — from cellular and molecular mechanisms through integrated systemic responses — with enough depth to support both examination preparation and clinical reasoning.

The book is organized into sections covering the cellular and molecular basis of medical physiology, nerve and muscle physiology, the central and autonomic nervous systems, endocrine physiology, reproductive physiology, cardiovascular physiology, respiratory physiology, renal physiology, and gastrointestinal physiology. Each chapter connects physiologic principles to clinical correlates, bridging basic science with medical application.

The Twenty-Sixth Edition includes updated figures and tables, revised clinical correlates reflecting current understanding of disease mechanisms, and updated content across endocrine, cardiovascular, and renal physiology chapters.

Medical students use Ganong's during their preclinical years and dedicated board review periods, while residents and clinicians return to it when reviewing the physiologic basis of conditions encountered in practice.
