Lymphedema: Innovations Final UPDATED
ACTUAL Exam Questions and CORRECT
Answers
Lymph fluid is composed of - CORRECT ANSWER -water
proteins- 1/2 of the protein circulating in the systemic system
cells- rbc, wbc, lymphocytes
waste products, cancer cells, cell debris, and bacteria
fat and fat-soluble vitamins
Types of lymph vessels - CORRECT ANSWER -capillaries
pre-collectors
collectors
trunks and ducts
Lymph capillaries - CORRECT ANSWER -main purpose is absorption of the lymphatic
load into the lymph system
-are larger and more permeable than blood capillaries, are able to absorb macro-molecules
what is responsible for opening and closing the endothelial junction of lymph capillaries -
CORRECT ANSWER -Anchoring filaments- semi-elastic fibers
-allow for lymph capillaries to stay open during high pressure to allow for passive influx
-close when pressure inside excess interstitial pressure - ensures that return of protein, water,
other macromolecules back to the cardiovascular system
-do not have valves
Lymph pre-collectors - CORRECT ANSWER -connection between the lymph capillaries
and the connectors
-contains smooth muscle and valves
, Lymph collectors - CORRECT ANSWER -transport lymph fluid to the lymph nodes and
the lymphatic trunks
-superficial (subcutaneous fat and skin) and deep collectors (muscle, joint, ligaments)
-passive fluid movement based upon the pressure gradient due to the one-way bicuspid valves
that keep flow moving from distal to proximal
lymphangion - CORRECT ANSWER -segment between the valves of a lymph collector
-activity is regulated by sympathetics and lymph volume
-lymphangioactivity- intrinsic contraction
lymph nodes - CORRECT ANSWER -filtration system- reabsorption of lymph fluid that
will be returned to the venous system
- can vary in shape and size
-primary identification site for immune system macrophages and lymphocytes
how many lymph nodes throughout the body - CORRECT ANSWER -600-800
-most are in the abdomen, head, and neck
lymph trunks - CORRECT ANSWER -largest transporter of lymph fluid to the organs and
extremities
-comes here after being filtered by the nodes
Lymph trunks of the lower body - CORRECT ANSWER -R and L lumbar runks
intestinal trunks
Lymph trunks of the upper body - CORRECT ANSWER -R and L jugular
R and L subclavian
R and L broncho-mediastinal
