Key Concepts & Definitions

  • Pathology: The branch of medicine that studies the causes, mechanisms, structural changes, and effects of diseases on the body.
  • Etiology: The study of the origin or cause of a disease, including genetic, infectious, environmental, or multifactorial factors.
  • Pathogenesis: The biological mechanism that leads to the development and progression of a disease after its initial cause.
  • Morphology: The structural and cellular changes in tissues and organs resulting from disease processes.
