Detailed explanation-1: -The red bone marrow produces B-lymphocytes (B cells) and T lymphocytes (T cells). B cells achieve immunocompetence (ability to recognize a specific antigen) in bone marrow. T cells migrate to the thymus gland, where they become immunocompetent.
Detailed explanation-2: -B cells-The second most common form of lymphocytes. These cells originate and become immunocompetent within the red bone marrow.
Detailed explanation-3: -B lymphocytes originate in the bone marrow; their goal is to recognize an antigen. Each of them responds to the antigen in a specific way, as it expresses specific antibodies on the membrane (IgM, CD79a, and CD79b).
Detailed explanation-4: -The primary parts of the immune system include the bone marrow and thymus. The bone marrow is extremely important to the immune system because all the body’s blood cells (including T and B lymphocytes) originate in the bone marrow. B lymphocytes remain in the marrow to mature, while T lymphocytes travel to the thymus.
