What will be an ideal response?
The innate immune system consists of phagocytic cells, natural killer (NK) cells, and various enzymes and serum proteins that are involved in the inflammation process. Inflammation is a response of the body to damaged tissue or infection characterized by swelling, pain, heat, and/or redness. The body's use of inflammation as a defense is like you taking a flame thrower to drive invaders out of your home. It's effective but you have to be careful about not setting your house on fire. If used too much or over a long enough period of time (e.g., chronic inflammation), you can cause more collateral damage to your house than to the invaders.
