ACOLS LYMPHATIC DRAINAGE 1 QUESTIONS &
ANSWERS
Cytopempsis theory - answer --active transport of larger molecules through membranes
-blood capillary (bc) walls are not permeable for proteins
-proteins may leave bc into tissue by way of cytopempsis
What is cytopempsis? - answer -describes the transportation of a substance into a cell
and through the cytoplasm in a vesicle followed by its release to the exterior w/out
utilization by the cell
How many grams of protein are there in each liter of plasma? - answer -75g
How many liters of blood does the average adult have? - answer -4-6 liters of blood
How many grams of protein constantly circulate the blood? - answer -300-400grams
What percentage of circulating blood proteins will leave the entire blood capillary
surface within a 24 hour period and move into the interstitial space? - answer -50%
T/f proteins are macromolecules - answer -true
T/f proteins are hydrophilic - answer -true (attracted to water)
T/f it is the lymphatic systems responsibility to removing proteins from the tissue
spaces? - answer -true
T/f under normal conditions proteins are returned to the venous system via the
lymphatic system - answer -true
Proteins are filtered by the ? - answer -lymph nodes
Lymphedema is - answer -high-protein edema
Once proteins are in the interstitium they become? - answer -lymphatic load
The body uses protein for? - answer -1.provide cell nutrition
2. Aid in immune defense (with albumin/globulin)
3.aid in blood coagulation (fibrinogen
Is the lymphatic system a closed or open system? - answer -ls is a an open circulatory
system
It is not a closed system
, What rout system does the ls provide - answer -the lymphatic system (ls) provides an
accessory rout by which lymph fluid can flow from tissues back to the bloodstream
What does lymph travel through to be filtered? - answer -lymph travels through many
successive lymph nodes to be filtered
Lymphedema is - answer -abnormal accumulation of protein and water in the interstitial
space
-resulting in inflammation, adipose tissue hypertrophy and fibrosis.
The consequent limb edema and induration can result in disfigurement, decreased
mobility, and/or limb dysfunction.
Lymphedema is what type of swelling? - answer -it is protein - rich swelling
T/f lymphedema is considered a disease process? - answer -true
Lymphedema is considered what type of insufficiency ? - answer -it is considered a
mechanical insufficiency of the ls
What is a mechanical insufficiency of the lymphatic system? - answer -this condition
occurs when there is a reduction of the total functional capacity of the lymphatic system,
which is insufficient even when the lymphatic load is normal or only moderately
increased.
What is the purpose of the lymphatic system? - answer -drain substances that cannot
be drained and reabsorbed by the blood system
-these substances are called= lymphatic loads (ll)
What does lymphatic load consist of? - answer -water, protein, cells, fat (long chain
fatty acid)
Lymphedema occurs due to an imbalance in what? - answer -the rate of lymph
production and/or lymph removal via the lymphatic system. Damage of lymph vessels,
nodes, or the malfunctioning of the system contributes to this imbalance - which may be
due to primary or secondary disorders of the lymphatic system
What is lymphatic load? - answer -the transport capacity is the maximum amount of
fluid the lymphatic system can carry. -in an undisrupted, healthy system, the transport
capacity exceeds the lymphatic load (almost 10x). --when the transport capacity
decreases due to lymphatic system dysfunction (in lymphedema patients), it can no
longer handle the excess lymphatic load and resultant lymphedema ensues.
What is transport capacity? (tc) - answer -the transport capacity is the maximum
amount of fluid the lymphatic system can carry.
