A&P II Review Questions Updated 2025/2026
1. What is the primary function of the lymphatic system?
(A) Circulate blood
(B) Return excess interstitial fluid to the bloodstream
(C) Produce hormones
(D) Digest food
Rationale: The lymphatic system's main role is to return excess interstitial fluid
to the bloodstream, maintaining fluid balance.
2. What are lymph nodes primarily responsible for?
(A) Filtering lymph and housing immune cells
(B) Producing red blood cells
(C) Conducting air
(D) Absorbing nutrients
Rationale: Lymph nodes filter lymph to remove pathogens and debris, housing
lymphocytes for immune response.
3. Which of the following is NOT a component of the lymphatic system?
(A) Lymph
(B) Lymph vessels
(C) Bone marrow
(D) Spleen
Rationale: While bone marrow is involved in blood cell production, it is not part
of the lymphatic system.
4. What is the primary role of lymph?
(A) Transport oxygen
(B) Transport lymphocytes and interstitial fluid
(C) Carry nutrients
(D) Filter blood
Rationale: Lymph transports lymphocytes and excess interstitial fluid back to
the circulatory system.
5. What organ is responsible for the maturation of T lymphocytes?
(A) Spleen
(B) Thymus
(C) Bone marrow

(D) Lymph nodes
Rationale: The thymus is where T lymphocytes mature and differentiate.
6. Which type of lymphocyte is primarily involved in antibody production?
(A) T cells
(B) B cells
(C) NK cells
(D) Macrophages
Rationale: B cells are responsible for producing antibodies in response to
specific antigens.
7. What is the function of the spleen in the lymphatic system?
(A) Filters blood and helps fight infections
(B) Produces antibodies
(C) Stores red blood cells
(D) Absorbs fats
Rationale: The spleen filters blood, removes old red blood cells, and helps
mount immune responses.
8. Which lymphatic structure collects lymph from the lower body?
(A) Right lymphatic duct
(B) Thoracic duct
(C) Lymph nodes
(D) Spleen
Rationale: The thoracic duct collects lymph from the lower body and left side of
the upper body.
9. What is the primary function of the tonsils?
(A) Filter blood
(B) Protect against pathogens entering through the mouth and nose
(C) Produce red blood cells
(D) Absorb nutrients
Rationale: Tonsils help protect against pathogens that enter through the oral and
nasal cavities.

10. What type of immunity is provided by antibodies produced by B cells?
(A) Cell-mediated immunity
(B) Humoral immunity
(C) Innate immunity
(D) Passive immunity
Rationale: Humoral immunity is mediated by antibodies produced by B cells in
response to antigens.
11. What is the role of lymphatic capillaries?
(A) Absorb interstitial fluid and transport it as lymph
(B) Filter blood
(C) Produce lymphocytes
(D) Conduct air
Rationale: Lymphatic capillaries absorb excess interstitial fluid and transport it
back to lymphatic vessels.
12. What is the primary function of the Peyer's patches?
(A) Absorb nutrients
(B) Monitor intestinal bacteria and prevent infection
(C) Filter blood
(D) Produce hormones
Rationale: Peyer's patches are lymphoid tissues in the intestines that monitor
bacterial populations and immune responses.
13. Which of the following is a characteristic of innate immunity?
(A) Non-specific response to pathogens
(B) Memory response
(C) Specific to antigens
(D) Long-lasting protection
Rationale: Innate immunity provides a non-specific response to pathogens
immediately upon exposure.
14. What is the role of macrophages in the lymphatic system?
(A) Produce antibodies
(B) Phagocytize pathogens and debris
(C) Transport lymph

A&P II Review Questions Updated 2025/2026
(D) Produce lymphocytes
Rationale: Macrophages engulf and digest pathogens and cellular debris,
playing a key role in immune response.
15. What is the significance of the lymphatic system in fat absorption?
(A) Absorbs fats from the digestive tract
(B) Filters toxins
(C) Produces hormones
(D) Regulates blood pressure
Rationale: The lymphatic system absorbs fats and fat-soluble vitamins from the
digestive tract through lacteals.
16. What is edema?
(A) Excess fluid in the bloodstream
(B) Excess fluid in tissues
(C) Increased blood pressure
(D) Dehydration
Rationale: Edema refers to the accumulation of excess fluid in the interstitial
spaces of tissues.
17. What is the role of the lymphatic vessels?
(A) Conduct blood
(B) Transport lymph from tissues to lymph nodes
(C) Filter air
(D) Produce hormones
Rationale: Lymphatic vessels transport lymph from tissues to lymph nodes and
eventually to the circulatory system.
18. What is the primary function of the thymus gland?
(A) Produce antibodies
(B) Mature T lymphocytes
(C) Filter blood
(D) Absorb fats
Rationale: The thymus is responsible for the maturation and differentiation of T
lymphocytes.
