Question

Quizplus · Accepted Answer

Lymphocytes are produced in the red bone marrow, and stem cells that can differentiate into all types of lymphocytes are also found in the red marrow. The thymus plays a role in the maturation of T lymphocytes, but not in their production from stem cells. The spleen filters blood and removes damaged blood cells and microbes, but it does not produce lymphocytes. Yellow marrow does not play a significant role in lymphocyte production.
