Introduction
• Inflammation – self-defense mechanism
• Protective response intended to eliminate the initial cause of cell injury as well as the necrotic cells and tissues resulting from the original insult
• Symptom of a wide variety of diseases

Phases of Inflammation
• Acute - vasodilatation & increased capillary permeability
• Delayed - infiltration of leukocytes and phagocytes
• Chronic Proliferative - tissue degeneration and fibrosis
