Question

Most body water is located in
A) plasma.
B) interstitial fluid.
C) cells.
D) lumens of organs open to the outside.

Accepted Answer

Most body water is located within cells, which make up approximately 60% of total body weight. The remaining 40% is split between interstitial fluid (around cells) and plasma (within blood vessels). Water is not typically found in the lumens of organs open to the outside, which are more likely to contain digestive juices, urine, or other bodily fluids.
