Which cells produce antibodies in the human body?

Last Updated: 26 Jun 2026

This question examines a fundamental concept of human anatomy, physiology, health, nutrition, disease, or body regulation that frequently appears in SSC CGL General Science. The human body works through coordinated organ systems. Restate the question in your own words, predict the answer before checking the options, and confirm that the explanation and correct-option field both point to B lymphocytes.

AT lymphocytes

BB lymphocytes

CNeutrophils

DMacrophages

Correct Answer: B lymphocytesYour Answer: B

Explanation

Therefore option B, B lymphocytes, is factually consistent with the stem, the marked correct index, and the explanation.✅ 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. 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. Neutrophils — Neutrophils are phagocytes that engulf and digest bacteria and debris; they don't produce antibodies. 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). Vaccines stimulate B cells to produce specific antibodies.

Important Notes

Read the complete stem and identify the exact demand: organ, gland, hormone, cell, tissue, nutrient, enzyme, pathogen, vector, deficiency disease, body fluid, or physiological function.
T lymphocytes, Neutrophils, Macrophages are eliminated here because none satisfies the precise requirement of the stem. Practising the reason for each rejection is more reliable than memorising only the correct choice.
Numerical biological facts often vary with age, sex, body size, and reference range. Use the standard approximate value expected in school-level competitive examinations and retain its unit.

FAQ

SSC CGL Human Body FAQs

Common questions and clear answers for this topic.

Which body systems are most important for SSC CGL preparation?

The digestive, circulatory, nervous, and skeletal systems appear most frequently, along with sensory organs and basic endocrine functions.

How many bones are there in the human body, and is this commonly asked?

Yes, the human body has 206 bones, and questions about the largest, smallest, and total bone count appear fairly often.

What kind of blood-related questions come up in SSC CGL?

Questions usually cover blood group compatibility, the role of platelets in clotting, and basic facts about blood pressure and heart function.

Do I need detailed biochemistry knowledge for the human body section?

No, most questions focus on what each organ does and why, rather than the detailed biochemical processes behind it.

How can I retain human body facts more effectively for the exam?

Linking facts to real-life observations, like why pulse is checked at the wrist, makes them easier to recall than memorizing textbook lines.
