White Blood Cell

Definition of White Blood Cell:
A blood cell that does not contain hemoglobin: a blood corpuscle responsible for maintaining the body's immune surveillance system against invasion by foreign substances such as viruses or bacteria.  White cells become specifically programmed against foreign invaders and work to inactivate and rid the body of a foreign substance.  White blood cells are composed primarily of neutrophils, monocytes and lymphocytes.  Lymphocytes are either T-cells or B-cells.  T-cells (CD3 cells) are divided into T-helper (CD4 cells) and T-suppressor/cytotoxic (CD8 cells) cells.
Also: WBC, White Blood Cells
