NURS 106 - LYMPHATIC SYSTEM EXAM QUESTIONS ANSWERED
CORRECTLY LATEST UPDATE 2026
What is another name for the lymphatic system? - Answers Lymphoid system
What components make up the lymphatic system? - Answers Lymphoid cells,
primary and secondary lymphoid tissues, and lymphatic vessels that contain lymph
(fluid)
How do lymphatic vessels function in the body? - Answers They are not continuous;
they start in the periphery and end in the heart, being close-ended.
What role do the holes in the lymphatic system serve? - Answers They act as a filter
system that picks up nutrients and dumps wastes.
How does the lymphatic system contribute to the immune system? - Answers It helps
maintain lymphocytes.
What is the relationship between lymphatic capillaries and fluid movement? -
Answers Capillaries carry more fluid to the periphery than they carry away, resulting
in more volume leaving the heart than returning.
Lymph - Answers Fluid content of lymphatic vessels, consisting of interstitial fluid,
lymphocytes, and macrophages.
Lymphatic vessels - Answers Vessels that begin at and pass through the lymphatic
tissues and organs.
Lymphoid cells - Answers Includes lymphocytes, phagocytes, and other cells.
Primary lymphoid tissues & organs - Answers Sites where lymphocytes are formed
and mature, such as red bone marrow and thymus.
Secondary lymphoid tissues & organs - Answers Sites where lymphocytes are
activated, including tonsils and MALT.
Lymph characteristics - Answers Clear, watery fluid that contains lymphocytes and is
95% water, higher in lymphocytes, rich in fats (triglycerides), and high in cells and
proteins.
Source of Lymph - Answers Lymph comes from excessive interstitial fluid that
entered lymphatic vessels.
Where do lymphatic vessels begin? - Answers Lymphatic vessels begin with
capillaries in peripheral tissues.
What happens to lymphatic capillaries as they combine? - Answers Capillaries
combine to form larger lymphatic vessels.
What must lymphatic vessels pass before merging into trunks? - Answers Lymphatic
vessels must pass through lymphatic nodes first.
What do lymphatic vessels merge into after leaving lymphatic nodes? - Answers
After leaving lymphatic nodes, the vessels merge into trunks.
What collects all the lymph from the trunks? - Answers Two ducts will collect all the
lymph from the trunks.
How does lymph enter the bloodstream? - Answers Trunks empty lymph into veins,
and from there, lymph enters the bloodstream to become part of the plasma.
What is the directionality of lymphatic vessels? - Answers Lymphatic vessels are
close-ended and only go one way, from the peripheral to the center.
What are the major lymphatic trunks? - Answers Jugular (neck/head), subclavian
(arm), bronchoediastinal (chest area), intestinal, and lumbar (abdominal area).
What is the largest lymphatic duct? - Answers The thoracic duct (left lymphatic
duct), which receives lymph from the upper left side of the body and both sides below
the diaphragm.
, What is the cisterna chyli? - Answers The base of the thoracic duct that receives
lymph from the abdomen, pelvis, and lower limb; it narrows upward into the thoracic
duct.
Where does the thoracic duct empty? - Answers Into the left subclavian vein.
What does the right lymphatic duct do? - Answers Receives lymph from the upper
right side of the body and empties into the right subclavian vein.
What forms the right lymphatic duct? - Answers The merging of the right jugular,
right subclavian, and right bronchomediastinal trunks.
How does the lymphatic system relate to the cardiovascular system? - Answers There
is a constant exchange of fluid; the lymphatic system carries fluid from the periphery
back to circulation, passing through lymph nodes and structures before returning to
the heart.
What is lymphedema? - Answers A condition resulting from the accumulation or
obstruction of lymphatic vessels, causing swelling.
How does lymphedema initially present? - Answers It acts like regular edema but can
stretch connective tissue and lose elasticity over time.
What risks are associated with untreated lymphedema? - Answers Increased risk of
vessel and skin damage, backflow, and hardening of the tissue.
What happens if too much pressure is put on an area affected by lymphedema? -
Answers The area may need to be drained to prevent complications.
Lymphoid cells - Answers immune cells found in lymphoid tissues
Lymphocytes - Answers specific cells that eat pathogens and add more body cells
T-cells - Answers lymphocytes that originate from the thymus and manage immune
response and attack
B-cells - Answers lymphocytes that originate from bone marrow and produce plasma
cells to secrete antibodies
NK cells - Answers natural killer cells from bone marrow that provide general
responses to all foreign cells
Antigens - Answers substances that T-cells and B-cells protect the body against
Macrophages - Answers cells that phagocytize foreign substances and activate T-
cells
Dendritic cells - Answers cells with a function similar to macrophages
Reticular cells - Answers supporting cells for tissues and other cells
Cytotoxic T cells - Answers T-cells that attack foreign cells or cells infected by
viruses
Helper T cells - Answers T-cells that activate and function for both T and B cells
Regulatory T cells - Answers T-cells that moderate both T and B cells
Memory T cells - Answers subset of T cells that respond to a previously encountered
antigen
Plasma cells - Answers differentiated B cells that produce and secrete antibodies
when stimulated
Lymphoid tissues - Answers connective tissues dominated by lymphocytes
Lymphoid nodules - Answers rounded clusters of lymphoid tissue where
lymphocytes are densely packed in areolar tissues with a germinal center
Mucosa-associated lymphoid tissue (MALT) - Answers a type of lymphoid tissue
Lymph nodes - Answers organs that are part of the lymphatic system
Thymus - Answers an organ where T-cells mature
MALT - Answers mucosa-associated lymphoid tissue
Lymphatic nodules - Answers Found in mucous membranes (in digestive,
respiratory, reproductive tracts)
