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.
