Endocrinology/VasopressinADH/EffectOfDecrease/basic

POINT!

With a decrease in the synthesis, secretion, and blood concentration of vasopressin (ADH), the number of water channels (in the tubule) decreases, which decreases the water reabsorption (from the tubule). The plasma osmolarity increases.

With a decrease in the synthesis, secretion, and blood concentration of vasopressin (ADH), the number of water channels (in the tubule) decreases, which decreases the water reabsorption (from the tubule). The plasma osmolarity-decreasing effect of water reabsorption becomes weaker, and plasma osmolarity increases (concentrated, hypertonic).
