Pathophysiology is the study of how diseases and disorders affect the normal functioning of the human body. It explains the biological and physiological changes that occur when cells, tissues, organs, or body systems are damaged by disease, injury, or infection. Understanding pathophysiology helps nursing students and healthcare professionals recognize disease processes, interpret clinical manifestations, and provide safe, evidence-based patient care.
This section covers the fundamental concepts of pathophysiology, including disease mechanisms, immune responses, inflammation, hypersensitivity reactions, and the pathophysiology of common medical conditions. The notes are designed to simplify complex concepts, strengthen clinical reasoning, and support both academic learning and nursing practice.
