Answer - D - Frank-Starling’s law, Starling’s law, and Frank-Starling’s mechanism are associated with myocardial contractions; each of these terms is interchangeably used. Starling’s law of the heart discusses the increase in myocardial contraction when the muscle fibers are stretched by increases in preload. The enhanced recoil results in more forceful expulsion of a larger amount of blood. This increase in stroke volume will then translate into improved cardiac output and eventually into improved blood pressure.
