Vascular and Leukocyte Events of Acute Inflammation in Pathology

The vascular and leukocyte events of acute inflammation describe how the body responds step by step to injury or infection. Blood vessels widen and leak fluid, then white blood cells (leukocytes) stick to the vessel wall, cross it, travel to the injury, and destroy the cause. Learning this fixed order explains why an injured area gets swollen and red, and why exudates and transudates differ.
