The Frank-Starling Law of the Heart states that
A) Increasing afterload increases the strength of contraction
B) The heart operates on the ascending limb of the length-tension curve
C) Increasing preload increases end systolic volume
D) Increasing preload increases the stroke volume of both ventricles
E) Increasing preload increases end diastolic volume

Question

Quizplus · Accepted Answer

The Frank-Starling Law of the Heart states that an increase in preload (end diastolic volume) leads to an increase in stroke volume due to the heart muscle fibers being stretched to an optimal length for contraction.
