Inflammation blood prevents this, as the shearing force along the periphery of the vessels moves cells in the blood into the middle of the vessel. The "cellular component" involves leukocytes, which normally reside in blood and must move into the inflamed tissue via "extravasation" to aid in inflammation. Some act as phagocytes, ingesting bacteria, viruses, and cellular debris. Others release enzymatic granules that damage pathogenic invaders. Leukocytes also release inflammatory mediators that develop and maintain the inflammatory response. In general, acute inflammation is mediated by granulocytes, whereas chronic inflammation is mediated by mononuclear cells such as monocytes and lymphocytes. Various leukocytes,
