Which term denotes the maintenance of body fluid balance?

• A. Fatigue
• B. Flushed
• C. Hydration
• D. Feasible

Answer: (C)

Maintaining body fluid balance is about hydration. Hydration means having the right amount of water in the body's compartments so cells, tissues, and organs can function properly. Adequate hydration supports blood volume, kidney function, temperature regulation, and metabolic processes, and it helps balance fluids and electrolytes as you lose water through sweat, urine, breath, and stool. When you’re well hydrated, you’re less prone to symptoms like dizziness or fatigue that come from dehydration, and you’ll notice regular urine output and healthy skin. The other terms describe different states—fatigue is tiredness, flushed is reddened skin, and feasible means something is possible. So the term that denotes the maintenance of body fluid balance is hydration.
