In the case of edema, excess fluid is held in which fluid compartment(s)?
intracellular fluid
interstitial fluid
intracellular fluid and interstitial fluid
blood plasma
The Correct Answer is B
A. Intracellular fluid: Intracellular fluid is inside the cells. Edema refers to fluid accumulation outside the cells, so this is incorrect.
B. Interstitial fluid: Edema is caused by the abnormal accumulation of fluid in the interstitial space, which is the space between cells in tissues.
C. Intracellular fluid and interstitial fluid: Edema is confined to the interstitial (extracellular) compartment, not intracellular.
D. Blood plasma: Although fluid may move from the plasma into the interstitial space, edema refers to fluid retention in tissues, not in the blood plasma.
