Pathophysiology is a medical science that studies the changes in the body's regulatory mechanisms that are related to the onset, development, and outcome of diseases. It combines the study of pathology (the causes and effects of disease) with physiology (how the body's systems function).
Pathophysiology combines pathology (the study of the causes and effects of disease) with physiology (the study of how systems of the body function). In other words, pathophysiology studies how diseases affect the systems of the body, causing functional changes that can lead to health consequences. Pathophysiology research aims to identify factors and mechanisms that are relevant for answering questions of why and how certain disorders and diseases develop.
The word pathophysiology comes from the Greek words pathos (suffering), physis (nature, origin), and logos (the study of).
Pathophysiology has four related components: Etiology: The study of the causes of health conditions and diseases Pathogenesis: The process by which a health condition develops Clinical manifestations: The visible signs and symptoms of a health condition
Pathophysiology focuses on the function and symptoms of diseased organs, and the processes that operate within an organism.
For example, cancer is a pathophysiological condition that requires abnormally high levels of nucleoside influx to support higher amounts of DNA synthesis. Pathophysiology is essential for those who work in any field of medicine.
