The life span of white blood cells is from hours to years, depending on the body's needs. If you have an infection, lymphocytes kill the germs (or at least they try) and some of them secrete antibodies that attack the germs. So in an infection, the number of white blood cells increases and they die faster. Some of them remember that the germ was in your body and the remain in your blood stream for years so if the germ appears again, they attack it with much more efficiency.
Red blood cells do not live any longer than 120 days.

Red Blood Cells have a span of 7-8 days...
But I think that White Blood cells don't have any span...and they get destroyed only after fighting germs.
