Question

Quizplus · Accepted Answer

A pure loss or gain of H₂O that is not accompanied by comparable solute deficit or excess in the body leads to changes in ECF (extracellular fluid) osmolarity. This means that the concentration of solutes in the ECF changes, which can disrupt normal cell function and lead to health issues. For example, dehydration can occur if there is a loss of water without a corresponding loss of solutes, leading to an increase in ECF osmolarity. Similarly, excessive water intake without excretion can lead to hyponatremia, which is a low concentration of sodium in the blood that can cause swelling of the brain and other serious health problems.
