Final answer:
Lymphocytes, including B cells, T cells, and natural killer (NK) cells, derive from lymphoid lineage cells. B cells mature in the bone marrow, while T cells mature in the thymus.
Step-by-step explanation:
Lymphocytes, including B cells, T cells, and natural killer (NK) cells, derive from lymphoid lineage cells. Lymphoid stem cells quickly migrate from the bone marrow to lymphatic tissues, such as the lymph nodes, spleen, and thymus, where their production and differentiation continue. B cells mature in the bone marrow, while T cells mature in the thymus.
