Much of today's medical care depends on a steady supply of blood from volunteer donors.
White Blood Cells are vital to prevent and fight infection.
White cells are made in the bone marrow and their life span varies from a few hours to many weeks.
White cells are essential to protect us from infection, but they are not often transfused because they are difficult to collect and their life span is so short.
