Which statement is true related to cardiac output?
 
 A slow heart rate would increases it with greater end diastolic volume, stroke volume and force of contraction
 Decreased venous return will result in increased end diastolic volume that would mean more blood leaving the heart.
 If a semilunar valve were partially blocked, the end systolic volume in the affected ventricle would go down and cardiac output would increase.
 Stroke volume, and therefore, cardiac output, increases if end diastolic volume decreases.
 A fast heart rate increases cardiac output more than any other factor.
