The volume in the pump when the pump piston is all the way down represents the end systolic volume.
<h3>
What is systolic volume?</h3>
End systolic volume is the volume of blood in a ventricle at the end of contraction, or systole, and the beginning of filling, or diastole.
End systolic volume is the lowest volume of blood in the ventricle at any point in the cardiac cycle.
Thus, the volume in the pump when the pump piston is all the way down represents the end systolic volume.
