Select the correct statement about cardiac output.
A) If a semilunar valve were partially obstructed, the end systolic volume in the affected ventricle would be decreased.
B) Stroke volume increases if end diastolic volume decreases.
C) A slow heart rate increases end diastolic volume, stroke volume, and force of contraction.
D) Decreased venous return will result in increased end diastolic volume.

Question

Quizplus · Accepted Answer

A slow heart rate allows more time for ventricular filling, increasing end diastolic volume, which can lead to an increased stroke volume and force of contraction due to the Frank-Starling mechanism.
