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