sodium, chloride, and potassium in cells and body fluids are examples of: question 54 options: phytates. electrolytes. condensat
Troyanec [42]

(b) electrolytes are what sodium, chloride, and potassium in cells and body fluids are examples of.

When dissolved in water or bodily fluids, a substance called an electrolyte separates into ions (particles having electrical charges). The ions sodium, potassium, calcium, chloride, and phosphate are only a few examples.

The many electrolytes include sodium, calcium, potassium, chloride, phosphate, and magnesium. They come from the meals you consume and the liquids you drink.

Your body's electrolyte levels might get too high or too low. When your body's water balance changes, this may occur. The amount of water you consume and lose should be equal. If something throws off this equilibrium, you can be dehydrated or have too much water on your body (overhydration).
