3.4. What electrolyte regulates extracellular fluid volume?

Sodium

Sodium, which is an osmotically active cation, is one of the most important electrolytes in the extracellular fluid. It is responsible for maintaining the extracellular fluid volume, and also for regulation of the membrane potential of cells.

What electrolytes are intracellular?

In the intracellular fluid, K+ and HPO4- are the major electrolytes. also of crucial importance in regulating fluid balance in the body. Sodium levels are extremely closely regulated by kidney function. most of it is reabsorbed in the kidney tubules.

What is the difference between intracellular and extracellular?

The significant difference between intracellular and extracellular is that one acts inside the cell, and the other acts outside the cell.
