Detailed explanation-1: -B lymphocytes become cells that produce antibodies. Antibodies attach to a specific antigen and make it easier for the immune cells to destroy the antigen. T lymphocytes attack antigens directly and help control the immune response.
Detailed explanation-2: -Bone marrow has been long thought to be a hematopoietic organ. However, it is well known that B cells are produced and matured in the bone marrow. Antigen-specific antibody producing, long-term lived plasma cells are largely found in the bone marrow. Thus, bone marrow contributes to humoral immune responses.
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: -There are two main types of T-cells: Helper T-cells stimulate B-cells to make antibodies and help killer cells develop. Killer T-cells or cytotoxic T-cells directly kill cells that have already been infected by a foreign invader.
