A)Cardiac reserve
B)End-diastolic volume
C)Afterload
D)Ejection fraction

Question

Quizplus · Accepted Answer

Preload is the amount of stretch on the ventricular muscle fibers just before systole, which is determined by the end-diastolic volume (EDV) of blood in the ventricles. Therefore, preload is synonymous with EDV. Cardiac reserve refers to the difference between the maximum cardiac output and the cardiac output at rest; afterload refers to the force against which the ventricles must contract to eject blood; and ejection fraction is the percentage of the EDV that is ejected during systole.
