Study Notes
Vascular Response to Injury
- Initial response to cellular injury is a brief, transient vasoconstriction.
- Release of chemical mediators (e.g., histamine) triggers vasodilation and increased capillary permeability.
- Vasodilation and increased capillary permeability lead to redness, heat, and swelling.
- Inflammatory exudates—a fluid containing plasma proteins and albumin—form.
- Cellular injury triggers a brief, transient vasoconstriction.
- Release of chemical mediators like histamine causes vasodilation and increased capillary permeability.
- Vasodilation and increased capillary permeability cause symptoms of redness, heat, and swelling.
- Inflammatory exudates are composed of serous fluid, containing plasma proteins and albumin.
