(e.g. bilirubin, fatty acids, hormones, etc.)
Explain how edema forms when albumin is low
Clinical relevance: When albumin level is low, water moves from the arteries to the interstitial space and cannot return to the veins; resulting in edema. Thus, any disease that decreases the levels of albumin in the plasma may result in edema.
T/F - Any disease that decreases albumin levels in plasma may result in edema
