INFLAMMATION:
Vasodilation

Occurs in response to the release of chemical
signals

Four major chemical signals:

Histamine – found in many cell types

Kinins – released from damaged tissue

INFLAMMATION:
Vasodilation

Occurs in response to the release of chemical
signals

Four major chemical signals:

Prostaglandins – intensify effects of histamine and
kinins


Help migration of phagocytes out of the blood and into
tissues
Leukotrienes – produced by mast cells

Promote adherence of phagocytic cells
