Pathological Changes
Structural and functional alterations in cells, tissues, and organs that occur as a result of disease processes or injury.
Pathological Changes
Pathological changes represent the observable and measurable alterations that occur in living systems as a result of disease processes, injury, or abnormal conditions. These modifications can manifest at multiple biological levels, from microscopic cellular changes to macroscopic organ dysfunction.
Levels of Pathological Changes
Cellular Level
- Alterations in cell membrane integrity
- Changes in cellular metabolism
- Apoptosis or necrosis patterns
- Abnormal cell division
Tissue Level
- Disruption of normal tissue architecture
- Inflammation responses
- Fibrosis and scarring
- Changes in tissue perfusion
Organ Level
- Alterations in organ size and shape
- Functional impairment
- Organ failure manifestations
- Structural deformities
Classification of Changes
Reversible Changes
- Cellular adaptation
- Early inflammatory responses
- Mild degenerative changes
- Tissue repair processes
Irreversible Changes
Diagnostic Approaches
