Study Notes
Vascular Response to Cellular Injury
- Initial Response: Brief, transient vasoconstriction occurs.
- Chemical Mediators: Release of histamine and other mediators triggers vasodilation.
- Increased Permeability: Vasodilation and increased capillary permeability result, leading to swelling.
- Clinical Signs: Redness, heat, and swelling are visible symptoms, linked to vasodilation and increased permeability.
- Inflammatory Exudates: Fluid containing plasma proteins (like albumin) leaks out, forming inflammatory exudates.
