According to the Frank-Starling law of the heart, the strength
of ventricular contraction is
directly proportional to the end-diastolic volume.
inversely proportional to the end-diastolic volume.
independent of the end-diastolic volume.
In the absence of compensations, the stroke volume will decrease when
blood volume increases
venous return increases.
contractility increases.
arterial blood pressure increases.
The volume of blood pumped per minute by the left ventricle is
greater than the volume pumped by the right ventricle.
less than the volume pumped by the right ventricle.
the same as the volume pumped by the right ventricle.
either less or greater than the volume pumped by the right
ventricle, depending on the strength of contraction.
