 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 the immune response.[1]

Types of White Blood Cell

The three main types of blood cell are Granulocytes(neutrophils, eosinophils, basophils), Monocytes, and Lymphocytes
Cell type  % of total white blood cells function
Lymphocyte 30 B lymphocytes makeantibodies.T lymphocytes target cells infected byviruses
Monocyte 5 Form macrophages for phagocytosis
Neutrophil 60 Phagocitosis
Eosinophil 2.5 Target parasites
Basophil 2.5 Secrete Histamine
