,1. Which type of immune response is characterized as being
immediate but non-specific?
- A) Adaptive immunity
- B) Innate immunity
- C) Acquired immunity
- D) Humoral immunity
ANS: B) Innate immunity
Rationale: Innate immunity is the first line of defense and
responds quickly to general features of pathogens.
2. What role do cytokines play in the immune response?
- A) They destroy pathogens directly.
- B) They act as signaling molecules.
- C) They provide structural support in tissues.
- D) They are receptors for antigens.
ANS: B) They act as signaling molecules.
Rationale: Cytokines are proteins that are used for
communication between cells in the immune system, helping
orchestrate the immune response.

,3. Which of the following cells is primarily responsible for the
production of antibodies?
- A) T-cells
- B) Neutrophils
- C) B-cells
- D) Macrophages
ANS: C) B-cells
Rationale: B-cells differentiate into plasma cells that produce
antibodies against specific antigens.
4. A failure of the body to recognize self from non-self can lead
to which condition?
- A) Immunodeficiency
- B) Autoimmunity
- C) Alloimmunity
- D) Hypersensitivity
ANS: B) Autoimmunity
Rationale: Autoimmunity occurs when the immune system
mistakenly attacks the body's own tissues.
5. Which type of hypersensitivity reaction is mediated by IgE?
- A) Type I
©2024/2025
, - B) Type II
- C) Type III
- D) Type IV
ANS: A) Type I
Rationale: Type I hypersensitivity is associated with the release
of IgE antibodies that lead to allergic reactions.
Fill-in-the-Blank Questions
6. The primary organ responsible for the maturation of T-cells is
the __________.
ANS: thymus
Rationale: The thymus is where T-cells mature and gain the
ability to recognize specific antigens.
7. _____________ are cells that engulf and digest cellular debris
and pathogens.
ANS: Macrophages
Rationale: Macrophages are key players in both innate and
adaptive immunity, acting as professional phagocytes.
