Consider the following statements regarding human immunity: 1. B lymphocytes mature in the bone marrow and are responsible for antibody-mediated humoral immunity. 2. T lymphocytes mature in the thymus gland and mediate cellular immunity by directly destroying infected host cells. Which of the statements given above is/are correct?

💡 Solution & Explanation

Both statements are accurate representations of adaptive immunity, where B cells originate and mature in bone marrow to produce circulating immunoglobulins, while T cells migrate to the thymus to differentiate into helper and cytotoxic populations that manage cell-mediated immune responses. Incorrect choices attempt to interchange maturation sites or immune functions. Active immunity can be acquired naturally through infection or artificially via vaccination.
