Which two factors are most likely to result in improved cardiac output?

Question

Quizplus · Accepted Answer

Cardiac output is the movement of blood out of the heart and into general circulation.Preload is the amount of blood in the left ventricle before contraction.This volume stretches the muscle of the left ventricle to result in a better force of contraction.So,to a point,greater preload helps improve cardiac output.Afterload is the pressure in the aorta that must be overcome for blood to leave the left ventricle.When this pressure is lower,the heart does not have to work as hard to move blood out of the left ventricle into the aorta.So,greater preload and reduced afterload tend to improve cardiac output.
