Inflammatory response

Histamines, Vasodilation, Edema, Diapedsis, Pus

Injured cells, Mast Cells, Platelets, Basophils release _______________ which leads to _________ resulting in increased blood flow and vascular permeability. This leads to leakage of plasma into the tissues which collects and is referred to as ______________.
