physiology

Question 1

lymphatic load

Answer 1

the amount of fluid that needs to be transported

Question 2

transport capacity

Answer 2

amount of lymphatic fluid that can be transported

Question 3

imbalance between load and capacity is bad,

Question 4

Load will increase as capacity decreases this will lead to…

Answer 4

lymphedema

Question 5

Venous insufficiency:

Answer 5

↑ load → ↑ lymphedema

Question 6

Lymph nodes removed:

Answer 6

↓ capacity → ↑ lymphedema

Question 7

U/L edema

Answer 7

deep vein thrombosis (DVT), lymphedema, post-thrombotic syndrome, arthritis,
Baker cyst

Question 8

B/L edema:

Answer 8

congestive heart failure (CHF), chronic venous insufficiency (CVI), lipedema,
renal and hepatic dysfunctions

Question 9

lymphedema

Answer 9

Chronic disorder characterized by excessive accumulation of lymph fluid in tissues of
one or more body regions

Question 10

Lymphedema is considered to be present if>10% increase compared to unaffected side
➤ Associated with disturbances of water and protein (increased concentrations of
both)

Question 11

Primary lymphedema

Answer 11

congenital or hereditary disease (Milroy disease)
Hypoplasia: fewer lymphatic vessels and smaller than normal
Hyperplasia
Aplasia

Question 12

Secondary lymphedema

Answer 12

is acquired,
Injury to one or more components of the lymph system
Causes
⚬ In the United States: cancer (breast, cervical)
⚬ Surgery (lymph node removal = lymphadenectomy), radiation, CVI,

tumors, trauma (burns, wounds), infection, complex regional pain syn-
drome (CRPS) (disuse)

⚬ Outside of the United States → filariasis (mosquito-born)
