1st star (illustration): Subject sweated. With water intake, plasma osmolarity decreases.(Synthesis, secretion, and concentration in blood of )vasopressin (ADH) (increases water channels. Water channels increase water reabsorption. Water reabsorption) decreases plasma osmolarity.
①(illustration): These are in the same direction (red).

② Since these effects are in the same direction (red), negative feedback decreases (blue) (the synthesis, secretion, and blood concentration of) vasopressin (anti-diuretic hormone, ADH). This decreases the number of water channels and the water reabsorption. The plasma osmolarity-decreasing effect of the water reabsorption becomes weaker. This will lead to a reverse in the decreased plasma osmolarity (diluted, hypotonic) produced by water intake, increasing it towards normal (baseline, isotonic) osmolarity.

Challenge Quiz

1.

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