Explain how changes in the blood vessels result in the redness and swelling seen at a site if the inflammation.
Histamine is released, histamine causes the arterioles to dilate which causes an increase in blood flow and the permeability of the membranes to increase allowing blood plasma to cause the swelling.
Histamine is released, histamine causes the Veins to dilate which causes an increase in blood flow and the permeability of the membranes to increase allowing blood plasma to cause the swelling.
Histamine is released, histamine causes the arterioles to constrict which causes an increase in blood flow and the permeability of the membranes to increase allowing blood plasma to cause the swelling.
