BIOL252: Human Anatomy & Physiology II
w/Lab Module 8: Fluid, Electrolyte, and Acid-
Base Balance Comprehensive Review
Question 1
How does proper fluid balance directly influence electrolyte balance in the body?
• By enhancing the secretion of hormones that degrade electrolytes
• By completely preventing the reabsorption of sodium in the kidneys
• Through the suppression of kidney function
• By only increasing the concentration of potassium in the extracellular fluid
• ---- - ✓✓ ANSWER--- The amount of fluid in a compartment will
affect the distribution and concentration of electrolytes
Correct Answer: The amount of fluid in a compartment will affect the
distribution and concentration of electrolytes
Rationale: Fluid and electrolytes are inextricably linked. The volume of
water (solvent) in a compartment directly determines the concentration
(molarity) of the electrolytes dissolved within it. If water volume drops
(dehydration), the electrolyte concentration artificially rises, even if the
absolute number of ions hasn't changed.
Question 2
Proper fluid balance is necessary to maintain optimal cellular functioning by
ensuring that cells are adequately hydrated, which supports enzymatic reactions,
nutrient uptake, and waste removal.
