Core coverage: stages of healing, inflammatory resolution, granulation tissue and
remodeling, type I-IV hypersensitivity mechanisms, mast cells and IgE, antibody-mediated
reactions, immune complexes, delayed T-cell responses, primary versus secondary
responses, memory B and T cells, affinity maturation, and booster responses.
, BIOL 3201 IMMUNOLOGY - QUIZ 7 PRACTICE
Quiz 7 Focus
This practice set targets Module 7: Healing, Hypersensitivity, and Immunological Memory. Questions emphasize
sequence, mechanism, and clinical-style recognition: how tissue repair progresses, how the four hypersensitivity
pathways differ, and why adaptive responses become faster and more effective after prior exposure.
01 Which event occurs first after a blood vessel is damaged during tissue injury?
A. Collagen remodeling over months
B. Formation of a mature scar before inflammation
C. Hemostasis with platelet activation and clot formation
D. Development of immunological memory
Answer: C
Explanation: Hemostasis begins immediately after vessel injury. Vasoconstriction, platelet activation, and the coagulation cascade limit
blood loss and create a provisional matrix for later repair.
02 During the early inflammatory phase of wound healing, which leukocyte is typically prominent first?
A. Plasma cell
B. Memory B cell
C. Neutrophil
D. Eosinophil in every wound
Answer: C
Explanation: Neutrophils are among the first leukocytes recruited to many acute wounds. They help control microbes and clear damaged
material before monocytes and macrophages become more prominent.
03 Which cell becomes especially important for clearing debris and coordinating later repair after the earliest
neutrophil response?
A. Naive B lymphocyte
B. Erythrocyte
C. Megakaryocyte
D. Macrophage
Answer: D
Explanation: Macrophages phagocytose debris and produce signals that help transition the tissue from inflammation toward repair. They
also influence fibroblasts, angiogenesis, and extracellular-matrix remodeling.
04 The proliferative phase of wound healing is characterized most strongly by:
A. Fibroblast activity, angiogenesis, and re-epithelialization
B. Only platelet aggregation
C. Complete disappearance of all extracellular matrix
D. T-cell receptor gene rearrangement
Answer: A
Explanation: The proliferative phase rebuilds tissue. Fibroblasts deposit matrix, new vessels grow, and epithelial cells migrate and
proliferate to restore surface continuity.
05 Which cell is a major source of collagen and other extracellular-matrix components during repair?
