Explain how antidiuretic hormone can help regulate an abnormal increase in solute concentration
in the extracellular fluid.
1. The release of antidiuretic hormone can regulate an increase in solute concentration by
causing reabsorption of water by the kidney. With reabsorption, blood water volume
increases, decreasing solute concentration
2. The release of antidiuretic hormone can regulate a decrease in solute concentration by not
absorbing water by the kidney. so blood water volume decreases,
3. none of this are correct
