According to the Frank-Starling law of the heart,
a. shortening cardiac muscle fibers prior to contraction causes more forceful contractions b. increasing venous return increases EDV, which leads to an increased stroke volume c. as cardiac output decreases, blood pools in the vasculature and increases arterial blood pressure d. the left ventricle must pump more blood than the right ventricle since the left ventricle must pump blood to more regions of the body e. the greater the stroke volume, the smaller the subsequent ESV, because as more blood is squeezed out, the heart cannot fill as completely.
