What are Some Examples of Pathophysiological Changes Observed in Tissues?
Various diseases manifest distinct histological changes, including:
- Inflammation: Characterized by the infiltration of immune cells, tissue edema, and changes in vascular permeability. - Neoplasia: Abnormal tissue growth, often seen as disorganized and uncontrolled proliferation of cells, with potential for invasion and metastasis. - Fibrosis: Excessive deposition of extracellular matrix components, leading to tissue stiffening and functional impairment. - Degeneration: Progressive loss of cell structure and function, often observed in neurodegenerative diseases. - Necrosis: Unplanned cell death resulting in tissue damage and inflammation.
