,Chapter 1: Introduction to the Immune System
PART A: MULTIPLE CHOICE QUESTIONS (1–40)
SECTION I: THEORY MCQs (1–20)
1.
A medical student is asked to explain why the immune system is considered essential not
only for protection against infection but also for maintaining internal stability. Which of the
following best captures the full scope of immune system function described in Chapter 1?
A. It produces antibodies to fight infections only
B. It identifies and eliminates pathogens while maintaining tolerance to self
C. It generates inflammatory fever responses
D. It stores immunological memory exclusively
Answer: B
Mechanism:
The immune system performs host defense, immune surveillance, tissue repair regulation,
and maintenance of self-tolerance.
A Too narrow (adaptive only)
C Only one component (inflammation)
,D Memory is adaptive only
2.
Innate immunity differs fundamentally from adaptive immunity because innate responses:
A. Improve with repeated exposure
B. Are mediated by antigen-specific receptors
C. Recognize conserved microbial patterns and act immediately
D. Require clonal expansion
Answer: C
3.
Adaptive immunity is characterized by:
A. Lack of specificity
B. Immediate action without prior exposure
C. Antigen-specific receptors generated before infection
D. Recognition of pathogen-associated molecular patterns only
Answer: C
4.
, The concept of self versus non-self discrimination is central because failure of this
distinction leads primarily to:
A. Immunodeficiency
B. Autoimmune disease
C. Immunological memory
D. Acute inflammation
Answer: B
5.
Which of the following represents a first-line defense mechanism?
A. Cytotoxic T lymphocytes
B. Plasma cell antibodies
C. Intact epithelial barriers
D. Memory B cells
Answer: C
6.
Pattern recognition receptors (PRRs) function to:
A. Generate antibody diversity
