Flashcards

Inflammatory Process

The body's multi-step response to tissue injury or infection involving vasodilation, increased permeability, chemotaxis, phagocytosis, and resolution.

Vasodilation

The expansion of blood vessels to increase blood flow to an affected area, aiding in delivering immune cells and nutrients.

Increased Vascular Permeability

The ability of blood vessels to allow proteins and immune cells to leak into tissues for healing.

Chemotaxis

The movement of white blood cells toward an injury site, guided by chemical signals called chemokines.
