White blood cells are a integral part of the bodies immune system, also know as leukocytes, they work as the second line of defense against bacterial and viral infections. White blood cells differentiate from bone marrow stem cells and differentiate into 1 of 5 different types of leukocyte. These are Lymphocytes, Eosinophils, Basophil, Neutrophils and Monocytes; all working together with differing objectives in a fight against infection [1]. Typically, the human body will contain 4500-10000 white blood cells, the number varies depending on the current level of stress on the person and whether they currently have any significantinfections. A very low white blood cell count is called leukopenia, this could be caused by bone marrow deficiency or even radiation therapy. Similarly, an exceptionally high white blood cell count is called leukocytosis. This can be caused by anemia, bone marrow tumors and leukemia.
