What are the signs of inflammation, and how does inflammation serve as a protective function?
What will be an ideal response?
The four signs of inflammation are swelling, redness, heat, and pain. The signs are caused by local vasodilation and increased capillary permeability. This is of benefit because the process helps to dilute harmful substances that may be present; brings in large quantities of oxygen, nutrients, and cells necessary for the repair process; and allows the entry of clotting proteins. Pain helps immobilize the injury.
