minimum urine output for adult 0.5mL/kg/hr ADH (antidiuretic hormone) - water retainer - vasoconstrictor (also called Vasopressin) - produced by hypothalamus - store and released from posterior pituitary ADH pathway - hypothalamus senses low blood volumed and increased serum osmolality - signal pituitary to release ADH - ADH causes kidney to retain water - water retention increases blood volume and decreases serum osmolality ANP (atrial natriuretic peptide) -...
