動画と音声での説明

① With sweating, plasma osmolarity increases. This is in the opposite direction ( blue) to the plasma osmolarity-decreasing effect of the reabsorption (through the water channels, which are increased by vasopressin, ADH).


② With sweating, (bluered) negative feedback facilitates (the synthesis, secretion, and blood concentration of) vasopressin (anti-diuretic hormone, ADH). This increases the number of water channels and the reabsorption of water. The plasma osmolarity-decreasing effect of the reabsorption increases, and the plasma osmolarity becomes adequate.
