Lymphedema Management UPDATED
ACTUAL Exam Questions and CORRECT
Answers
What does the lymphatic system do? - CORRECT ANSWER - Drains fluid from
interstitial tissues and brings it back to the blood stream
How many liters does it move a day? - CORRECT ANSWER - 2-3 liters
What is lymph fluid made of? - CORRECT ANSWER - mainly water and protein but also
misc cells and fat
What does lymphatic load mean? - CORRECT ANSWER - fluid that can't be drained or
reabsorbed by the blood system
What are the duties of lymphatic system? - CORRECT ANSWER - -continuous circulation
of fluid in interstitial space
-safety valve for fluid overload
-balance of protein and water (homeostasis of extracellular environment
-cleansing of interstitial fluid
How thick is lymphatic system? - CORRECT ANSWER - 1 epithelial layer thick
What is the smallest component in lymphatic system? - CORRECT ANSWER - lymphatic
capillaries
How does fluid get into the lymphatic system? - CORRECT ANSWER - lymphatic
capillaries are connected by anchoring filaments. With fluid build up tissue pressure increases
pulling on the filaments. This opens the jx btw cells and lymphatic fluid enters the system
through this opening
,Trace lymph fluid travel starting from lymph capillaries to lymph nodes? - CORRECT
ANSWER - Travels from capillaries to lymph pre-collectors. From pre collectors goes to
lymph collectors. Then lymph is transported through collectors via muscle contraction of the
lymph anions. When fluid enters the lymph angion - muscle is stretched causing muscle to
contract. fluid enters nodes via afferent lymph collectors and leaves via efferent lymph collectors
What do lymph pre collectors look like? - CORRECT ANSWER - closely related to blood
vessels with a layer of smooth muscle and valves that allow uni-directional flow
T or F. Does lymph have its own flow rate? - CORRECT ANSWER - True.
What's another name for the lymph angion? - CORRECT ANSWER - the heart
compartment
What is another name for angiomotoricity? - CORRECT ANSWER - lymph pulse
What is the contraction frequency of lymph angion when at rest? under stress? - CORRECT
ANSWER - 6-10 per min at rest
20 per min during stress
What are the two primary functions of lymph nodes? - CORRECT ANSWER - Protection
- filter out harmful material in lymph fluid
Immune Response - produce lymphocytes
Where are lymph nodes located? - CORRECT ANSWER - neck, digestive system, axilla,
and groin
Approximately how many lymph nodes in body? - CORRECT ANSWER - 700!!!!
, Axillary lymph nodes drain what? - CORRECT ANSWER - upper extremity and thorax
Inguinal lymph drains what? - CORRECT ANSWER - abdominal, lumbar, gluteal regions
exterior genitalia and lower extremity
Cervical lymph nodes drain what? - CORRECT ANSWER - head and neck areas
Where does lymph travel after the nodes? - CORRECT ANSWER - It is transported to
larger lymphatic trunks
How long is thoracic duct and what does it connect to? - CORRECT ANSWER - thoracic
duct is 10-18 inches long and connects with left venous angle which drains into R side of heart
What two areas does the mammary gland lymph drain to? - CORRECT ANSWER -
axillary lymph nodes (¾)
parasternal lymph nodes (¼)
What is a common site for metastases? - CORRECT ANSWER - axillary lymph nodes
The maximum amount of lymph transported by the lymphatic system working as hard as
possible over a given length of time is called what? - CORRECT ANSWER - Transport
Capacity
Why is transport capacity normally 10 times higher than the normal lymphatic load? -
CORRECT ANSWER - So that we have the capacity to respond to trauma
What is the difference between the normal lymphatic load and the transport capacity is called
what? - CORRECT ANSWER - Functional Reserve
