Question

Which equation is most accurate?
A)Extracellular fluid volume + interstitial fluid volume = whole body fluid volume
B)Intracellular fluid volume + interstitial fluid volume = extracellular fluid volume
C)Extracellular fluid volume - interstitial fluid volume = plasma volume
D)Plasma volume + intracellular fluid volume = extracellular fluid volume
E)Total body fluid volume - intracellular fluid volume = interstitial fluid volume

Quizplus · Accepted Answer

C) Extracellular fluid volume - interstitial fluid volume = plasma volume. This equation is most accurate because the extracellular fluid consists of two main components: the interstitial fluid (fluid between cells) and the plasma (the liquid part of blood). Therefore, if you subtract the volume of interstitial fluid from the total extracellular fluid volume, you get the plasma volume.
