Pathology is the study of structural and functional abnormalities that are expressed as diseases of organs and systems. The science began in the 19th century when Rudolf Virchow (the father of modern pathology) proposed that injury to the cell, the smallest living unit of the body, was the root of all disease. This remains the basis for pathology today which has now expanded to understand the molecular nature of these interactions.
