If a person were stranded for two days with virtually no drinking water, you would expect the following to occur.
A) production of dilute urine
B) a decrease in antidiuretic hormone (ADH) secretion
C) a decrease in aldosterone secretion
D) production of concentrated urine

Question

Quizplus · Accepted Answer

When a person is stranded with no drinking water, their body will try to conserve water as much as possible. This is done by increasing the secretion of antidiuretic hormone (ADH), which causes the kidneys to reabsorb more water from the filtrate and produce concentrated urine. In addition, the renin-angiotensin-aldosterone system is also activated, causing an increase in aldosterone secretion, which promotes water reabsorption in the distal tubules of the kidneys. Therefore, the most likely outcome of being stranded with no drinking water would be the production of concentrated urine (D). The production of dilute urine (A) and a decrease in ADH secretion (B) would be unlikely in this situation. While the renin-angiotensin-aldosterone system increases aldosterone secretion, it still promotes water reabsorption in the kidneys, making a decrease in aldosterone secretion (C) an unlikely outcome as well.
