Increased antidiuretic hormone (ADH) secretion is likely after ________.
A) drinking lots of pure water
B) sweating-induced dehydration increases plasma osmolarity
C) eating a small sugary snack
D) blood pressure becomes abnormally high

Question

Quizplus · Accepted Answer

Increased ADH secretion is a response to increased plasma osmolarity (concentration of solutes in blood). Sweating-induced dehydration increases plasma osmolarity, causing the release of ADH to decrease water loss in urine. Drinking lots of pure water would decrease plasma osmolarity, leading to decreased ADH secretion. Eating a small sugary snack and blood pressure becoming abnormally high are not directly related to ADH secretion.
