NURS 5315 Exam Test 2 Mod 3 Clean, corrected
Q&A study set (2025)
Organs of the immune system CORRECT ANSWER:
• Bone marrow
• Thymus
• Spleen
• Lymph nodes, tonsils, Peyer patches
Bone marrow function in the immune system CORRECT
ANSWER: Responsible for production of immune cells and the
maturation of B cells
Thymus function in the immune system CORRECT ANSWER:
Provides site for T-cell differentiation, maturation, and selection (shrinks
as we grow)
Spleen function in the immune system CORRECT ANSWER:
• Contains blood-filled sinuses that filter antigens and cells from the
blood
• Red pulp (red blood cell storage and turnover)
pg. 1
,2
• White pulp (where immune cell interaction occurs)
• Those without a spleen are at increased risk for infection
Lymph nodes function in the immune system CORRECT
ANSWER: Antigen interaction with immune cells
5 types of immunity CORRECT ANSWER:
1. Natural (Innate resistance)
2. Active Acquired
3. Passive Acquired
4. Humoral
5. Cell-mediated
Normal function of T-lymphocyte CORRECT ANSWER:
• Develop into several subsets that identify and kill target cells (T-
cytotoxic)
• Regulate immune response by helping clonal selection process (T-
helper)
• Suppress/limit immune response (T-regulatory)
pg. 2
, 3
Normal function of B-lymphocyte CORRECT ANSWER: Develop
into plasma cells that produce antibody
Natural Immunity (AKA innate resistance immunity) CORRECT
ANSWER: (Innate, non-specific defense mechanisms present from
birth)
Active Acquired Immunity CORRECT ANSWER: Produced by
host after exposure to an antigen (basis of vaccinations)
Passive Acquired Immunity CORRECT ANSWER: Acquired via
the transfer of antibodies or T cells to recipient (mother to fetus, rabies)
Humoral Immunity CORRECT ANSWER: Conferred by B cells;
provides immunity against some viral infections, toxin-induced diseases,
and diseases caused by pneumococci/meningococci/hemophilus
Cell-mediated Immunity CORRECT ANSWER: Conferred by T-
cells; active against cells infected with intracellular bacteria or viruses;
responsible for organ transplantation rejection
Antigen (def) CORRECT ANSWER: Describes a molecule that can
react with binding sites on antibodies or antigen receptors on B & T cells
pg. 3
