| With water intake, the (red→blue) negative feedback facilitates (the synthesis, secretion, and blood concentration of) vasopressin (anti-diuretic hormone, ADH). |
① Water intake decreases plasma osmolarity, and reabsorption (through the water channels, which are increased by vasopressin, ADH) increases plasma osmolarity. These effects are in the same direction (red).
② Since these effects are in the same direction (red), negative feedback inhibits (blue) (the synthesis, secretion, and blood concentration of) vasopressin (anti-diuretic hormone, ADH). This decreases the number of water channels and the reabsorption of water. The plasma osmolarity-decreasing effect of the reabsorption decrease, and the plasma osmolarity becomes adequate.

Water intake increases decreases plasma osmolarity, and reabsorption (through the water channels, which are increased by vasopressin, ADH) increases decreases plasma osmolarity. Since these effects are in the same opposite direction, with sweating, negative feedback facilitates inhibits (the synthesis, secretion, and blood concentration of) vasopressin (anti-diuretic hormone, ADH).
