The role of bradykinin in process of inflammation is:
Functions of Bradykinin: 1. Increases vascular permeability 2. Contraction of smooth muscles 3. Dilation of the blood vessels 4. Pain when injected into the skin Out of these actions of bradykinin, the increase in vessel permeability is a better answer as it is the hallmark of acute inflammation.
Vasoconstriction
Bronchodilation
Smooth muscle relaxation
Increased vascular permeability
Chemical mediators in plasma: Kinin system
