State
Inflammation dilates local blood vessels and increases their permeability, delivering more phagocytes and plasma proteins to an injury or infection site, producing redness, heat, swelling, and pain.
Show
Histamine release from damaged tissue drives the vessel dilation that produces inflammation's visible redness and swelling.
Watch for
Inflammation is a coordinated defensive response, not tissue malfunction, even though its symptoms feel uncomfortable.
