2.76B understand how water is reabsorbed into the blood from the collecting duct

Re-absorption of water at the Collecting Duct:
-Water that is filtered by kidney is re-absorbed into blood by the Collecting Duct, depending on levels of ADH produced by the Pituitary Gland.
-More ADH: more water re-absorbed into Collecting Duct
-Less ADH: less water re-absorbed into Collecting Duct
