Question: 1 / 400

Where does water primarily follow according to physiological principles?

Oxygen

Electrolytes

Energy

Salt

Water primarily follows electrolytes, specifically salts, due to the principle of osmotic balance. In physiological contexts, when salt is present in a solution, it creates a concentration gradient. Water tends to move toward areas of higher solute concentration to dilute the solute, which is often salt or other electrolytes. This movement of water is crucial in maintaining homeostasis within the body, ensuring that cells remain in an environment that supports their necessary functions.

The movement of water in response to electrolytes is essential in many physiological processes, such as hydration, nutrient absorption, and waste removal. Hence, it's accurate to say that water follows the presence of salts, as they play a key role in regulating the movement of water within bodily fluids and tissues.
