LYMPHEDEMA MANAGEMENT EXAM QUESTIONS
AND ANSWERS
What exactly does the lymphatic system do? - ANSWER Drains fluid from the
interstitial tissues and returns it to the bloodstream.
How many liters does it move each day? - ANSWER 2–3 liters
What is lymph fluid composed of? - ANSWER: mostly water and protein, but also
other cells and fat.
What does "lymphatic load" mean? - A fluid that cannot be emptied or reabsorbed
by the circulatory system.
What are the functions of the lymphatic system? - ANSWER: Continuous
circulation of fluid in interstitial space.
-a safety valve to prevent fluid excess
-protein-water balance (extracellular environment homeostasis)
- cleaning of interstitial fluid
How thick is the lymphatic system? - ANSWER 1 Epithelial layer thick.
What is the smallest component of the lymphatic system? - Answer: lymphatic
capillaries.
How does fluid enter the lymphatic system? - The lymphatic capillaries are joined
by anchoring filaments. With fluid buildup, tissue pressure increases, pressing on
,the filaments. This opens the junction between cells, and lymphatic fluid enters the
system via this opening.
Trace lymph fluid travels from lymph capillaries to lymph nodes. - ANSWER
Travels from capillaries to lymph pre-collectors. From pre collectors to lymph
collectors. The lymph is then carried through collectors via muscular contraction of
the lymph anions. When fluid enters the lymph region, the muscle is stretched and
contracts. Fluid enters nodes via afferent lymph collectors and exits through
efferent lymph collectors.
What do lymph pre-collectors look like? The ANSWER is closely connected to
blood veins with a layer of smooth muscle and valves that allow unidirectional
flow.
T or F. Does lymph have its flow rate? - ANSWER: True.
What is another name for the lymph node? - Answer: the heart chamber.
What's another term for angiomotoricity? - Answer lymph pulse.
When the lymph anion is at rest, how frequently does it contract? Under stress? -
ANSWER 6-10 per minute at rest.
20 per minute amid stress.
What are the two main functions of lymph nodes? - ANSWER Protection: filter out
hazardous materials in lymph fluid.
Immune ANSWER - produces lymphocytes.
Where are the lymph nodes located? - ANSWER Neck, Digestive System, Axilla,
and Groin
, What is the approximate number of lymph nodes in the body? - ANSWER 700!!!
What do axillary lymph nodes drain? - Answer: upper extremities and thorax.
What does the inguinal lymph drain? - ANSWER: abdominal, lumbar, gluteal,
external genitalia, and lower extremity.
What do cervical lymph nodes drain? - Answer the head and neck areas.
Where does the lymph go after the nodes? - ANSWER It is transferred into bigger
lymphatic trunks.
How long is the thoracic duct, and what does it link to? - ANSWER Thoracic duct
is 10-18 inches long and links with the left venous angle, which empties onto the
right side of the heart.
Which two locations do the mammary gland lymph drain to? - Answer: axillary
lymph nodes (¾).
Parasternal lymph nodes (¼)
What is a common location for metastases? - Answer: axillary lymph nodes.
