Answer: A - The two phases of acute inflammation are vascular and cellular. Initially, the vascular phase constricts the blood vessels. This is followed by the widening of blood cells to increase blood flow to the area of infection. During the cellular phase, leukocytes migrate to the infected tissue by chemotaxis. The leukocytes will devour particle matter and then turns into phagosomes. If there is a transition from acute inflammation to chronic inflammation, the area will become filled with macrophages.
