Flashcards
Acute inflammation
Acute inflammation
A rapid response of the body to injury, involving the delivery of leukocytes and plasma proteins to the site of injury.
Vasodilation in acute inflammation
Vasodilation in acute inflammation
The process where blood vessels widen, allowing more blood to flow to the injured area.
Increased Vascular Permeability in acute inflammation
Increased Vascular Permeability in acute inflammation
The process where blood vessels become more permeable, allowing fluid and proteins to leak out into the surrounding tissues.

Study Notes
Acute Inflammation
- Rapidly delivers leukocytes and plasma proteins to injury sites.
- Leukocytes clear invaders and digest necrotic tissues.
Components of Acute Inflammation
- Vascular Changes:
- Vasodilation leads to increased blood flow.
- Increased vascular permeability allows plasma proteins to exit the circulation.
- Cellular Events:
- Leukocyte recruitment and emigration to injury sites.
- Leukocyte activation to eliminate the offending agent.
- Neutrophils are the primary leukocytes in acute inflammation.
Causes of Acute Inflammation
- Infections
- Trauma (blunt and penetrating)
- Physical agents
- Chemical agents
- Tissue necrosis
- Foreign bodies (splinters, dirt, sutures, crystal deposits)
- Immune reactions (hypersensitivity reactions) against environmental substances or "self" tissues.
Outcomes of Acute Inflammation
- Resolution: Regeneration and repair.
- Limited or short-lived injury.
- Minimal tissue damage.
- Injured tissue capable of regeneration.
- Chronic Inflammation:
- Restoration of normal structure and function.
- May lead to scarring.
