White blood cells (WBCs), also called leukocytes or leucocytes, are the cells of the immune system that are involved in protecting the body against both infectious disease and foreign invaders.All leukocytes are produced and derived from a multipotent cell in the bone marrow known as a hematopoietic stem cell.he number of leukocytes in the blood is often an indicator of disease, and thus the WBC count is an important subset of the complete blood count. The normal white cell count is usually between 4 and 11 Ã 10 9 /L. In the US this is usually expressed as 4,000â11,000 white blood cells per microliter of blood.
The majority of white blood cells are produced in the bone marrow, where they outnumber red blood cells by 2 to 1. However, in the blood stream, there are about 600 red blood cells for every white blood cell. There are several different types of white blood cells. Granulocytes are one type of several types of white blood cells that are in fact used in more specialized transfusion therapy. Granulocytes and monocytes protect against infection by surrounding and destroying invading bacteria and viruses, and lymphocytes aid in the immune defense system.
