Inflammatory response plays a critical role in immunity. When tissues are damaged, the inflammatory response is initiated, and the immune system becomes mobilized. The immune cells of the innate immune system (i.e., neutrophils and eosinophils) are the first recruited to the site of tissue injury or damage via blood vessels and lymphatic system, followed by macrophages.
If the damage occurs near the surface of the skin, redness and swelling may be visible. Pain and warmth are also symptoms of inflammation.
The goals of the inflammatory response are to:
- Prevent initial establishment of infection or remove damaged tissue.
- Prevent the spread of infection or repair damaged tissue.
- Recruit effector cells if the immune cells of the innate immune system cannot control infection or repair damaged tissue.
- Mobilize effector cells (T and B lymphocytes).
