In response to low blood plasma Na⁺,reduced ADH will decrease water volume in the blood to match lower Na⁺ concentration while increased aldosterone will increase Na⁺ reabsorption to match the higher water volume of blood.

Question

Quizplus · Accepted Answer

This is the correct physiological response to maintain electrolyte and water balance in the body. A decrease in blood plasma Na+ concentration triggers a reduction in ADH secretion, leading to decreased water reabsorption in the kidneys and a decrease in blood volume. On the other hand, an increase in aldosterone secretion enhances Na+ reabsorption from the renal tubules, leading to an increase in blood volume. This helps to match the water volume in the blood with the lower Na+ concentration.
