Which of the following processes occurs during the inflammation phase of the healing process?
A. The immune system releases histamines, which cause vasodilation and increased capillary permeability, resulting in local redness and swelling.
B. White blood cells are forced away from the injury site, thus allowing an increase in the flow of red blood cells, resulting in increased blood flow.
C. The blood vessels in and around the injury site constrict, which forces bacteria and other microorganisms away, thus preventing significant infection.
D. The veins and arteries at the injury site constrict and platelets aggregate, which stops bleeding and causes a temporary increase in the size of the wound.
