The amount of ADH that is secreted by the posterior pituitary gland varies with changes in blood
A) osmolarity
B) oxygenation
C) glucose level
D) decarboxylation

Question

Quizplus · Accepted Answer

ADH secretion is primarily regulated by changes in blood osmolarity, which is a measure of the concentration of solutes in the blood. When blood osmolarity increases (due to dehydration, for example), ADH secretion increases, leading to water retention by the kidneys and decreased urine output. Conversely, when blood osmolarity decreases (due to overhydration, for example), ADH secretion decreases, leading to increased urine output. Oxygenation, glucose level, and decarboxylation do not directly affect ADH secretion.
