Sample Question
What is the muscle pump and how does it aid in venous return? How would this affect SV?

The muscle pump has no effect on venous return and SV.

The muscle pump prevents pooling and edema. It also directs blood back towards the heart. It aids in venous return because venous return is the amount of blood going back to the heart from the venous system, so the muscle pump does that. SV is enhanced by increased venous return during exercise.
