Excitability - Answer- the ability of non-pacemaker heart cells to respond to an electrical impulse that begins in pacemaker cells. Depolarization - Answer- occurs when the normally negatively charged cells within the heart muscle develop a positive charge. Conductivity - Answer- the ability to send an electrical stimulus from cell membrane to cell membrane. As a result, excitable cells depolarize in rapid succession from cell to cell until all cells have depolarized. Ex: the wave of depol...

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) -...
