1.
With sweating water intake 正解!, negative feedback increases (the synthesis, secretion, and blood concentration of) vasopressin (anti-diuretic hormone, ADH). This increases decreases 正解! the number of water channels, which increases decreases 正解! the water reabsorption from the tubule and the plasma osmolarity increases decreases 正解! towards normal (baseline).
