Maintenance of normal extracellular fluid volume depends largely on the extracellular concentration of _____ ions.

Question

Quizplus · Accepted Answer

Sodium and chloride ions play a major role in the maintenance of normal extracellular fluid volume through the regulation of osmotic pressure and water balance. Sodium ions are the main electrolyte in extracellular fluid, while chloride ions accompany sodium ions to maintain electrical neutrality. Together, they help to regulate blood pressure, maintain proper hydration, and ensure normal physiological function.
