Inflammation
Physical effects resulting from activation of the immune system
Inflammation
Inflammation (from Latin: inflammatio) is part of the biological defence response of body tissues. Inflammatory immunovascular responses can be triggered by a broad range of stimuli, including physical trauma, "dead, damaged, malfunctioning or stressed tissues", pathogens, irritants, toxins, overuse, autoimmunity, allergens, and foreign bodies (e.g. silica and asbestos). The five cardinal signs are heat, pain, redness, swelling, and loss of function (Latin calor, dolor, rubor, tumor, and functio laesa). Inflammation is a generic response, and therefore is considered a mechanism of innate immunity, not adaptive immunity. It involves immune cells, blood vessels, and molecular mediators. The function of inflammation is to eliminate the initial cause of cell injury, clear out damaged cells and tissues, and initiate tissue repair. Too little inflammation can lead to progressive tissue destruction by the harmful stimulus (e.g. bacteria) and compromise the survival of the organism, but too much...
