In the process of inflammation, which is NOT a characteristic?

• A. Increased blood supply to the area.
• B. Decreased capillary permeability.
• C. Migration of white blood cells.
• D. Appearance of acute-phase reactants.

Answer: (B)

Inflammation involves vasodilation to boost blood flow, increased capillary permeability to allow fluid, proteins, and immune cells to leave the vessels and enter tissue, movement of white blood cells out of the vessels toward the site of injury, and the liver producing acute-phase reactants in response to cytokines. The statement that does not fit is decreased capillary permeability; in inflammation, permeability actually increases to facilitate defense and healing. The other processes described—more blood flow, leukocyte migration, and acute-phase reactant production—are typical features of acute inflammation.
