Quizplus · Accepted Answer

T cells originate in the bone marrow but mature in the thymus, where they undergo a process of selection to ensure they can recognize and attack foreign substances, such as viruses or bacteria, without attacking the body's own cells. B cells also originate in the bone marrow but mature in different parts of the body and produce antibodies instead of attacking foreign substances directly. Telomeres are the protective caps on the ends of chromosomes, and antigens are substances that trigger an immune response.
