Pathology
The scientific study of diseases, their causes, processes, development, and consequences in living organisms.
Pathology
Pathology is the cornerstone of medical science that investigates the essential nature of disease and the structural and functional changes it causes in organisms. As a discipline, it bridges the gap between basic scientific method research and clinical practice.
Core Branches
Anatomical Pathology
- Study of gross and microscopic tissue changes
- Includes histology examination
- Utilizes surgical pathology techniques
- Incorporates autopsy findings
Clinical Pathology
- Analysis of bodily fluids
- Integration with laboratory medicine
- Includes hematology and clinical chemistry
- microbiology testing
Historical Development
The field emerged from ancient medical practices but gained scientific rigor during the Renaissance. Key historical figures like Rudolf Virchow established cellular pathology as a fundamental principle, demonstrating that all diseases result from changes at the cellular level.
