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