What: "White blood cells are like vacuum cleaners or Hoovers. They gobble up infection and dirt and also release chemicals into the area that attract more white blood cells and open up the capillaries and veins supplying blood to the area. Once they have gobbled the bacteria and dirt up, they die. If too many accumulate in one area, the body can't clear the dead cells fast enough and a collection of dead white blood cells and bacteria form, called an abscess. Sometimes abscesses have gas in them from the bacteria fermenting the dead tissue."
