,What is the term used to describe the filling of the ventricles with blood?
A) Afterload
B) Preload
C) Stroke volume
D) Cardiac output
B) Preload
Afterload refers to:

must overcome to pump the blood into circulation
B) The amount of blood returning to the heart
C) The volume of blood filling the ventricles before contraction
D) The electrical impulses that set the heart rate
A) The amount of pressure needed to pump blood out of the ventricles; the resistance the left ventricle
must overcome to pump the blood into circulation
