Final answer:
ADH, also known as antidiuretic hormone, becomes saturated (rate-liming) at a certain point. ADH regulates the amount of water excreted by the kidneys by causing water reabsorption from the kidney tubules.
Step-by-step explanation:
ADH, also known as antidiuretic hormone, becomes saturated (rate-liming) at a certain point. ADH regulates the amount of water excreted by the kidneys by causing water reabsorption from the kidney tubules.
When the concentration of ADH becomes saturated, the water channels, aquaporins, that ADH inserts into the kidney tubules are unable to carry out further reabsorption and urine volume increases.
