What our notes say
- fluid; ICF), while the remainder is in the extracellular fluid (ECF) (Davidson's Essentials of Medicine - 2nd)
- Vitamin D and parathyroid hormones act to ensure that ECF(extracellular fluid) calcium and phosphorus concentrations are at appropriate levels to permit mineralization (Rickets)
- The maintenance of normal volume and normal composition of the extracellular fluid is vital to life. (fluid and electrolyte balance disturbances)
- Sodium – principal extracellular cation; maintains plasma osmolality, extracellular fluid (ECF) volume, and drives water movement. (Sodium, potassium and calcium disorders)

Practice questions on Extracellular Fluid
Which electrolyte is the most abundant cation in extracellular fluid?
- Calcium
- Potassium
- Sodium
- Magnesium Correct
Answer: C. Sodium (Na+) is the predominant cation in extracellular fluid (normal: 135-145 mEq/L), while potassium is the main intracellular cation.
