Answer #1

A denarvared heart can increase it output while exercising as well as at rest .

This occur as

  1. When Exersice is done body will stimulate teh production of the catecholamines which mainly the epinephrine and norepinephrine will stimulate the cardiac muscle cells and cause the increase in heart rate and blood supply to tissue . This is the effect of circulating catacholamines
  2. The parasympathetic nervous system is the one that control or reduce the heart rate . As denervation occur it will cause nothing to control the Heart rate m so then heart rate will increase very much

These will cause increase in output as the caridiac output is stroke volume× heart rate
