INTEG - LYMPHEDEMA EXAM QUESTIONS AND
ANSWERS
What's the most common cause of lymphedema in the United States? - Answer:
Breast cancer.
ANSWER Lymphedema vs. Edema
- Chronic, abnormal buildup of protein and water in interstitial spaces, protein-rich
swelling
- Unilateral (typically).
Edema:
- Symptoms are frequently bilateral and symmetrical.
What is the purpose of the lymphatic system and how does it function (vague
answer)? - ANSWER: A one-way system that filters and breaks down contaminants
in the blood that cannot drain.
begins in interstitial space and concludes by being returned to the venous system
via the right and left subclavian veins.
What does the lymphatic system carry (also known as lymphatic load)? -
ANSWER Water, proteins, cells, fat—anything too big to be taken in by the venous
capillaries.
2-4 litres of water taken daily and returned to the venous system.
, What are the steps of the lymphatic system, and what does each section do? -
ANSWER Initial vessels: superficial dermis; picks up lymphatic burden.
Pre-collectors: attach collectors to the early capillaries.
Collectors are superficial fatty tissues that convey lymph to nodes.
Nodes: lymph fluid thickening and proactive immune ANSWER.
Trunks are enormous lymph collectors.
Venous Angles: the point when lymph is returned to the subclavian veins.
Describe the initial lymph vessels and pre-collectors (such as their composition)
and their overall function - ANSWER Initially, endothelial cells form
one-cell-thick capillaries.
Pre-collectors: smooth structures in the deeper dermis.
FXN: absorbs fluid into the lymphatic system.
Lymph collectors carry lymph to lymph nodes through valves and lymphangion.
When lymph arrives, lymphangions stretch and then smooth muscles contract to
convey it through the valves.
What are the three primary functions of lymph nodes? - ANSWER: Filters
hazardous fluids.
Immune cells create antigen-stimulated lymphocytes.
