What is the osmolarity of urine the influence of ADH?: (A) 50 mOsmol / L, (B) 800 mOsmol / L, (C) 1200 mOsmol / L, (D) 500 mOsmol / L
Answer is C. ADH will increase water reabsorption into medulla,making low volume,concentrated urine of 1200 - 14000 mOsmol / L
Urine osmolarity in absence of ADH is 30 - 50 mOsmol / L
