Study Notes
Pathology
- Pathology is the science of disease study, dealing with five components: definition, causes, mechanisms (pathogenesis), morphologic changes (gross and microscopic), and complications.
Inflammation
- Definition: Inflammation is a protective immune-vascular response, a reaction of living tissue against injury.
- Causes of inflammation: infectious agents, immunological, tissue necrosis, chemical and physical agents, and nutritional factors.
Components of Inflammation
- Cause
- Immune cells
- Blood vessels
- Chemical mediators
Purpose of Inflammation
- Eliminate the cause of inflammation
- Clear necrotic cells
- Initiate repair
