inflammation

deals with infected organisms where they have entered the body

sends out disttress signals to WBC's to come to the scene

redness-due to vasodilation of blood vessels in the infected area to increase blood flow

heat - result of increased blood flow

swelling - extra blood forces fluid into the damaged tissues - allows immune cells from blood to get to site of infection

pain - swollen tissues press on nerves

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
