Study Notes

Pathological Processes and Etiologies

Determining the pathological process aids in identifying the cause (etiology).
Five key pathological processes are: degeneration/necrosis, inflammation and repair, circulatory disorders, disorders of growth and deposits, and pigmentations.
These pathological processes are broadly categorized by their nature, affecting all cells, tissues, and organs.
Potential etiologies behind these pathological processes include: genetic/inherited factors, infections (bacterial, viral, parasitic), metabolic issues, toxic exposures, autoimmune responses, idiopathic causes (unknown origin), and iatrogenic causes (resulting from medical treatment).
General pathology focuses on the main five pathological processes induced by various damaging agents and applies to all cells, tissues, and organs
Systemic pathology delves into the system-specific disease processes. While building upon general pathological processes, it examines the unique responses to injury in each tissue and organ, and the distinct diseases associated with specific systems and species.
