Question

Quizplus · Accepted Answer

When extracellular water has an excess of sodium ions, it leads to an osmotic gradient that draws water out of the cells and into the extracellular space. This causes the intracellular fluid to decrease, and the cells lose water and shrink. Therefore, the correct choice is D where cells lose intracellular fluid and shrink.
