Answer:The Frank-Starling law states that the greater the volume of blood discharged from the heart, the greater the pressure required to discharge the blood

Basically, the FSL states that the greater the stroke volume of the left ventricle will increase, as the volume of the the ventricles increases due to ventricular contraction, leading to systolic contraction.

If the volume of the blood in the Ventricle is increased, the blood volume stretches the ventricular walls and the ventricle contracts.The amount of blood ejected from the ventricle increased(stoke volume).Therefore, the higher the contraction of the ventricles, Myocyte stretch, the more the volume of blood in the ventricle pushed, and the more the amount of the blood ejected from the ventricle as Stroke Volume.

Explanation:
