What is the role of the preload in the cardiovascular system?
- It is the amount of blood pumped out of the heart after one contraction
- It is the tension on the ventricular wall muscle made by end-diastolic volume (EDV) (correct)
- It is the difference in end-diastolic and end-systolic volume
- It is the amount of blood ejected from the left ventricle per minute
