How does the sodium potassium pump help maintian fluid balance?

The sodium potassium pump is constantly a work in each cell of the body to keep sodium and potassium levels in cell fluids even. This pump allows sodium ions which are abundant outside of the cell, to diffuse into the cell, and potassium, which is abundant inside the cell, to diffuse to outside the cell. If this process were to cease, sodium ions would build up inside your cells, which would attract water and ultimately cause the cell to explode.
