Answer - B - The pressure in the ventricle at the end of diastole is referred to as preload, also known as end-diastolic. Preload influences the force of the next contraction. 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.
