Check All That Occur During Inflammation

Question

Check all that occur during inflammation.
A)Chemical mediators cause vasodilation
B)Blood flow is decreased to the area
C)Vascular permeability is decreased
D)Fibrin walls off the infected area
E)Complement attracts phagocytes to the area

Accepted Answer

During inflammation, chemical mediators such as histamine cause vasodilation, increasing blood flow to the area, not decreasing it, which contradicts choice B. Vascular permeability actually increases, allowing immune cells and proteins to enter the affected tissue, contradicting choice C. Fibrin can wall off the infected area to prevent the spread of infection, and complement proteins attract phagocytes to the area, aiding in the immune response.
