Example immune system multiple-choice questions

Which white blood cells differentiate into plasma cells that secrete antibodies?B lymphocytes (B cells). Activated B cells become plasma cells, which are the antibody-producing cells of adaptive immunity.

Which immune cells does HIV primarily infect and destroy?CD4+ T helper cells. Losing them weakens coordination of the adaptive immune response, which is why HIV causes immunodeficiency.

What is the main role of the complement system?It tags pathogens for destruction and forms membrane attack complexes that can lyse bacteria. It works alongside antibodies and phagocytes.

True or false: memory B cells let the immune system respond faster on a second exposure to the same antigen.True. Memory cells persist after the first infection and drive a quicker, stronger secondary response.

Which innate immune cells are among the first to arrive at an infection site and engulf microbes?Neutrophils. These phagocytes are among the earliest responders and destroy bacteria by engulfing them.

Frequently asked questions

How many practice questions should I make from one chapter on the immune system?

Aim for a set you can finish in one sitting, around 15 to 20 questions per chapter. Covering innate versus adaptive immunity, key cell types and antibody function gives the set good range.

What makes a good multiple-choice question about the immune system?

Each question should test one idea, such as which cell produces antibodies, with plausible wrong options like T cells or neutrophils. Explanations should say why the wrong options fail, not only what the right one is.

Does the free plan include exports?

No. The free plan gives you 3 generations a month and lets you study in the browser. Export to PDF, DOCX, Anki and CSV is part of the Plus plan at $39/year or $7.99/month.
