    • Inflammation
      • Destroys invading microbes
        • attacked by intact white cells
      • Damaged blood cells released histamines
        • Cause arterioles to dilate
        • Increases blood flow in and permeability of  the capillaries
      • Causes oedema
        • Plasma fluid, white blood cells and antibodies leak from blood into tissue
    • Lysozyme Acton
