Changing conductivity (IMAGE) University of Delaware Caption This diagram depicts the way conductivity will change as blood cells break. The yellow dots represent electrons. The red circles represent blood cells. Viewing the graphic from left to right, one can see that when more blood cells are present, fewer electrons are able to get across. As blood cells break, there are fewer barriers and the blood becomes more conductive, making it easier for electrons to move from one side to the other.
