White blood cells

Blood cells that help fight infection and other diseases. An important part of the body's immune system, white blood cells (WBCs) are made in the bone marrow (the soft, sponge-like tissue in the center of most bones). White blood cells are classified according to their structure and function. Two of the most common types are lymphocytes and neutrophils. A low WBC count is called leukopenia. A high WBC count is called leukocytosis. White blood cells are also called leukocytes.
