An immunologist studies which system?

• A. Immune system
• B. Circulatory system
• C. Endocrine system
• D. Skeletal system

Answer: (A)

An immunologist studies the immune system, the body's defense network against pathogens. This includes innate defenses such as barriers and phagocytes and adaptive defenses like B and T lymphocytes and antibodies. Key organs involved are bone marrow (where immune cells originate), thymus (T cell maturation), spleen, lymph nodes, and other lymphoid tissues. The immune system works by recognizing non-self, mounting inflammatory and cellular responses, and creating immune memory. While the circulatory system helps transport immune cells and the skeletal system houses bone marrow, the focus here is on how the immune system defends the body, not on those other systems.
