Answer: All of the above.
Explanation: Inflammation process is part of the immune response to fight against infection or injury. It works together with the complement system that promotes the ability of antibodies and phagocytes to remove microorganisms and damaged cells from site of infection. Cytokines are produced by T-helper cells and macrophages to regulate inflammation by producing cytokines that sends positive feedback for the initiation of inflammation process. Promoting the production of chemicals, proteins and enzymes for chemotaxis and diapedesis of phagocytes.
Basically during inflammation the site of infection or injury will change colour and turn red, it will swell and cause the production of pyrogens which will result in fever symptoms due to raise of body temperature.
