Which of the following statements is false? a. The sympathetic nervous system releases epinephrine and norepinephrine, which are positive chronotropic and inotropic agents. b. The endocrine system regulates cardiac output through chronotropic and inotropic hormones and through hormones that regulate water balance .c. The parasympathetic nervous system releases acetylcholine,which is a strongly negative inotropic agent. d. Factors such as electrolyte concentrations, body temperature,and age all affect cardiac output.
