Answer - B - Preload influences the force of the next contraction. The pressure in the ventricle at the end of diastoles is referred to as preload. This is based on Starling’s law of the heart, which states that the more the myocardial muscle is stretched, up to a limit, the greater its force of contraction will be. Another name for preload is end-diastolic volume.
