innate immunity is NOT only physical defenses

inflammation triggered by damaged cells phagocytes accumalate to increase rate at which bacteria and debris can be dealt with by phagocytosis ruptured local cells, mast cells and basophills release alarm chemicals such as histamines and kinins causes vasodilation attract other cells from blood to the area leads to signs of inflammation
