 White Blood Cells (leucocytes) are all of  the cells in the blood which, unlike Red Blood Cells, do not contain hemoglobin. They make up about 1% of blood and have an average life time of 4 days.They are formed from heamatopoetic (multipotent) stem cells in the bone marrow. From there the white blood cells migrate into the tissues in response to chemokines to take place in theimmune response.
