Question

Generally speaking the movement of Na+ determines the
A) blood pH.
B) blood glucose.
C) secretion of PTH.
D) movement of water.

Accepted Answer

The movement of Na+ is closely linked to the movement of water, because Na+ is an osmotically active solute. In other words, when Na+ moves across a membrane, water will follow due to the osmotic gradient created. This can affect the distribution of water throughout the body and influence various physiological processes, such as blood pressure and volume. Na+ does not directly affect blood pH, blood glucose, or secretion of PTH.
