Quizplus · Accepted Answer

Lymphocytes are responsible for specific immune responses and participate in two types of immunity: (1)humoral immunity,which is mediated by B lymphocytes,and (2)cellular immunity,which is mediated by T lymphocytes.B lymphocytes,or B cells,originate in the bone marrow and are also thought to mature there.B cells perform in antibody production.T cells are produced in the bone marrow,but they migrate to the thymus for maturation; then,most of them travel and reside in lymphoid tissues throughout the body.They live longer than B cells and participate in long-term immunity.The natural killer cell is a third type of lymphocyte,thought to be a differentiated form of the T lymphocyte.It is responsible for surveillance and destruction of virus-infected and malignant cells.
