important to read.
¨ Why would concentrated urine be a problem? ¨ Think of the serum OSM (osmolality) ¨ Why does the urine concentrate? ¤ In response to OSM……….. ¨ ↑ Serum OSM ↑ ADH = concentrated urine ¨ ↓ Serum OSM ↓ ADH = dilute urine ¨ Hypothalamus is responding to serum OSM ¤ Mostly happens in the loop of Henle n H20 excreted or NOT
