Endocrinology/VasopressinADH/SummaryOfEffect/basic

POINT!

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

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