Which of the following factors determine cardiac stroke volume?
I.ventricular preload
II.ventricular afterload
III.ventricular contractility

Question

Quizplus · Accepted Answer

All three factors, ventricular preload, ventricular afterload, and ventricular contractility, contribute to determining cardiac stroke volume. Ventricular preload refers to the filling of the ventricles before contraction, ventricular afterload is the resistance that must be overcome to eject blood from the ventricles, and ventricular contractility refers to the strength of the heart's contractions. Together, these factors determine the amount of blood pumped out of the heart with each beat.
