Challenge Quiz
Sweating 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).
