Answer #1

Answer

As exercise progresses, muscular activity increases venous return. This increases the preload on the right ventricle.

One factor that influences venous return is skeletal muscle pump.
Exercise increases skeletal muscle contraction. This increases venous return.
Due to increased venous return, the amount of blood in the right side of heart is more.
During atrial systole, right ventricular filling increases the tension in cardiomyocyte.
Preload is the stretch of ventricular cardiac muscle tissue before its contraction due to amount of blood present.
Hence, venous return increases preload on right ventricle.
