d)/
Over 95 percent of the body’s potassium is in cells. In contrast, most of the body’s sodium is outside the cells in blood and other fluids. How does this happen? Cells actually pump Na+ out and K+ in via the "Na-K Pump."
This Pump is in the mb of all body cells, and one of its most important functions is PREVENTING CELLULAR SWELLING. If Na+ is not pumped out, water accumulates in the cell, causing it to swell and ultimately burst.
The Na-K Pump also functions to maintain the electrical charge within the cell, this is particularly important to muscle and nerve cells.
Is that correct?
