More water is reabsorbed in blood due to _________ ?

Correct answer: A. More anti-diuretic hormone

  • A. More anti-diuretic hormone
  • B. Lesser anti-diuretic hormone
  • C. Active functioning of pancreas
  • D. Inactivity of pituitary gland

Explanation

Antidiuretic hormone, or ADH, increases water reabsorption by making the collecting ducts more permeable to water, so more water returns to the blood. Students may choose lesser ADH because they associate it with reduced urine formation, but lesser ADH actually causes more water to remain in urine.
