A
The kidneys are major organs of fluid balance, excreting up to 1,500 mL of water daily, based on the amount of fluid ingested and amount of waste or solutes excreted. When an extracellular fluid volume deficit occurs, certain hormones (antidiuretic hormone, aldosterone, and renin) are released to prompt the kidneys to conserve water. The interaction of these hormones with renal function serves as the body's compensatory mechanism to maintain homeostasis.
