Q.Where are B-cells and T-cells produced in the human body? How do they differ from each other? Mention any two differences.

Step 1. The chapter states that both B and T lymphocytes are produced in the bone marrow.

Step 2. From there, B lymphocytes (B cells) stay in the bone marrow until they are mature, then circulate to the blood, lymph nodes and spleen.

Step 3. T lymphocytes, by contrast, leave the bone marrow and complete their maturation in the thymus gland before joining B cells in the same peripheral tissues.

Step 4. Difference 1 — site of maturation: B cells mature in the bone marrow itself, while T cells must migrate to and mature in the thymus. …

State the shared origin (bone marrow) then contrast maturatio …

• Saying T cells are 'produced' in the thymus rather than merely maturing there after originating in bone marrow …
