What Effect Do Aldosterone and Antidiuretic Hormone (ADH)have on Urine

question 66

Multiple Choice

What effect do aldosterone and antidiuretic hormone (ADH) have on urine volume?

• A) Because water reabsorption in the distal and collecting tubules doesn't require ADH, the aldosterone mechanism must work separately from the ADH mechanism to maintain homeostasis of the fluid content in the body.
• B) Both aldosterone and ADH decrease distal and collecting tubule absorption of sodium, which in turn causes an osmotic imbalance that drives the reabsorption of water from the tubule.
• C) Because water reabsorption in the distal and collecting tubules requires ADH, the aldosterone mechanism must work in concert with the ADH mechanism if homeostasis of the fluid content in the body is to be maintained.
• D) Both aldosterone and ADH increase distal and collecting tubule absorption of sodium, which in turn causes an osmotic imbalance that stops the reabsorption of water from the tubule.
