EFFECTS OF ANTIDIURETIC HORMONE (ADH) ON URINE FLOW RATES: 

What would happen to the urine flow rate if the subjects (in the Diuresis lab) who drank water were given intranasal desmopressin (i.e., a synthetic antidiuretic hormone) just after drinking the water? EXPLAIN why this occurs, including the effects of desmopressin in the renal tubular cells. 

Please note that intranasal administration enables the drug to rapidly enter the bloodstream via the nasal capillaries.
