Which cells produce antibodies in the human body?
Last Updated:
AT lymphocytes
BB lymphocytes
CNeutrophils
DMacrophages
Correct Answer: B lymphocytesYour Answer: B
✅ Correct Answer: B — B lymphocytes
B Lymphocytes (B cells) are responsible for producing Antibodies (Immunoglobulins). When B cells encounter antigens (foreign substances like bacteria or viruses), they differentiate into Plasma cells which secrete antibodies. These antibodies specifically bind to the antigen and mark it for destruction. This is called Humoral Immunity.
❌ Why other options are wrong:
• A. T lymphocytes — T cells are responsible for Cell-mediated immunity (directly killing infected cells); they do NOT produce antibodies. T-helper cells assist B cells.
• C. Neutrophils — Neutrophils are phagocytes that engulf and digest bacteria and debris; they don't produce antibodies.
• D. Macrophages — Macrophages are phagocytes that engulf pathogens and also present antigens to T cells; they don't produce antibodies.
📝 Important Note: B lymphocytes = Antibody production (Humoral immunity). T lymphocytes = Cell-mediated immunity. There are 5 types of antibodies (IgG, IgM, IgA, IgD, IgE). Immunoglobulin G (IgG) is most abundant. Vaccines stimulate B cells to produce specific antibodies. SSC CGL immunology key concept.
