Actually it is two: sodium and potassium because they and their regulators are so intertwined. But a very, very simple answer to your question, water always follows sodium.
The principal ions in the ECF are sodium, chloride, and bicarbonate. The ICF contains an abundance of potassium, magnesium, and phosphate ions, plus large numbers of negatively charged proteins.
Despite the differences in the concentration of specific substances, the osmotic concentrations of the ICF and ECF are identical. Osmosis eliminates minor differences in concentration almost at once, because most cell membranes are freely permeable to water.
Sodium is the dominant cation in the ECF (Extra Cellular Fluid)
Potassium is the dominant cation in the ICF (Inter Cellular Fluid).
Two general rules concerning sodium balance and potassium balance are worth noting:
The Most Common Problems with Electrolyte Balance Are Caused by an Imbalance between Gains and Losses of Sodium Ions.
Problems with Potassium Balance Are Less Common, but Significantly More Dangerous than Are Those Related to Sodium Balance.
What else can I help you with?
Is the excretory system responsible for maintaining the volume and composition of most body fluids?
Yes, the excretory system plays a crucial role in maintaining the volume and composition of body fluids by filtering out waste and excess substances from the blood to be excreted as urine, thus helping to regulate electrolyte balance, pH levels, and fluid volume in the body.
What is the principal cation of the ECF?
The principal cation of the extracellular fluid (ECF) is sodium (Na+). Sodium plays a critical role in maintaining fluid balance, nerve function, and muscle contraction in the body.
Is potassium found in the intracellular fluid?
Yes, potassium is the main cation (positively charged ion) found in the intracellular fluid of our body. It plays a crucial role in various cellular functions, such as maintaining cell volume and regulating the transmission of nerve impulses.
Lymph is an example of which type of fluid?
Lymph is an example of interstitial fluid that flows through the lymphatic system. It consists of water, proteins, fats, and white blood cells, and plays a crucial role in maintaining fluid balance and immunity in the body.
The chief ion used to maintain the volume of fluid outside cells is?
The chief ion used to maintain the volume of fluid outside cells is sodium (Na+). Sodium plays a crucial role in regulating fluid balance by helping to maintain appropriate osmotic pressure and water distribution in the body.
What is the electrolyte that plays the largest role in maintaining body fluid volume is?
sodium
What is the largest volume of water in the body is?
plasma

Large fluid-filled organelle in mature plant cells?
Central vacuole. It occupies most of the cell's volume and plays a role in storing water, maintaining turgor pressure, and storing nutrients and waste products.
What is the primary extracellular fluid cation in the body?
The primary extracellular fluid cation in the body is sodium (Na+). It plays a crucial role in maintaining fluid balance, nerve function, and muscle contraction.
The mineral that is found primarily in the intracellular fluid compartment is?
Potassium is the mineral that is found primarily in the intracellular fluid compartment. It plays a crucial role in maintaining fluid balance, nerve function, and muscle contractions within cells.
What is the principal cation of the ECF?
The principal cation of the extracellular fluid (ECF) is sodium (Na+). Sodium plays a critical role in maintaining fluid balance, nerve function, and muscle contraction in the body.

How might hemodilution be avoided?
Hemodilution can be avoided by minimizing the volume of intravenous fluids administered during surgery or medical procedures, thereby maintaining the patient's blood volume. Additionally, the use of techniques such as blood conservation strategies, including cell salvage and preoperative autologous blood donation, can help reduce the need for transfusions. Maintaining normovolemia through careful monitoring and adjustment of fluid administration also plays a crucial role in preventing hemodilution. Lastly, employing regional anesthesia techniques can reduce blood loss and the need for excessive fluid replacement.
