Detailed explanation-2: -Which of the following is true of cardiac output? A Cardiac output equals the volume of blood pumped out of the ventricles per heart beat.
Detailed explanation-3: -Several factors increase cardiac output, including thyroid hormones, hypercalcemia (increased Ca2 + levels in the blood), and sympathetic activation. Similarly, any factor that decreases cardiac output will decrease blood pressure and blood flow.
