What is LYMPHOCYTES?

LYMPHOCYTES help the body remember previous invaders and recognize them if they return to attack again.
Lymphocytes begin their life in BONE MARROW.
Some stay in the marrow and develop into B lymphocytes (B cells); others travel to the thymus and become T lymphocytes (T cells). These two cell types have different roles.
B LYMPHOCYTES produce antibodies and help alert the T lymphocytes.
T LYMPHOCYTES destroy compromised cells in the body and help to alert other leukocytes.
NATURAL KILLER (NK) cells are also lymphocytes. NK cells recognize and destroy cells that contain a virus.
