Best answer


The Frank-Starling law holds true only for a heart with healthy cells, and within certain physiological limits. In a heart which is failing, the more the cells are stretched, the weaker is the force that is exerted back to pump out blood, which usually occurs due to the lower amount of calcium released during each heartbeat.

  • What is the Frank-Starling law of the heart?

  • Frank-Starling Law of the Heart Explained. The Frank-Starling law mechanism can be defined as ‘an intrinsic adaptive response which serves to adjust each ventricular output to its inflow by increasing the force of contraction of the myocardium proportionally to any increase in the length of the muscle fibers’, i.e.,…

  • What is the Frank Starling law in cardiac hemodynamics?

  • The Frank-Starling Law is the description of cardiac hemodynamics as it relates to myocyte stretch and contractility. The Frank-Starling Law states that the stroke volume of the left ventricle will increase as the left ventricular volume increases due to the myocyte stretch causing a more forceful systolic contraction.

  • What is Frank Starling’s law of tension?

  • The Frank-Starling law states that the force or tension developed in a muscle fiber depends on the extent to which the fiber is stretched. In a clinical situation, when increased quantities of blood flow into the heart (increasing preload), the walls of the heart stretch.

  • What is the Frank Starling relationship in the heart?

  • Within a normal physiologic range, the more the myocardial fibers are stretched, the greater the tension inthe muscle fibers and the greater force of contraction of the ventricle when stimulated. The Frank-Starling relationship is the observation that ventricular output increases as preload (end-diastolic pressure) increases.

    The Frank-Starling law,also known as Starling鈥檚 law,or Frank-Starling law of the heart,is aphysiological theorywhich states that,鈥榯he strength of the heart鈥檚 systolic contraction is directly proportional to its diastolic expansion,with the result that under normal physiological conditions the heart pumps out of the right atrium all the blood returned to it without letting any back up in the veins.鈥?/div>Frank-Starling Law of the Heart Explained – Bodytomy

  • What is Frank Starling’s law of contraction?

  • Frank-Starling Law. The Frank-Starling law describes the relationship between the force of contraction and the initial length of muscle cells. The sarcomere length associated with the most powerful contraction is 2.2 渭m because there is maximal overlap of myofilaments in this configuration.

  • What is the Frank-Starling law?

  • The Frank-Starling law is an important part of our understanding of the human heart鈥檚 physiology. In this article, we will learn about the various facets of the law, and how the heart deals with changes in the rate of blood flow. Did You Know?

  • Which best describes the Frank-Starling law?

  • What best describes the Frank-Starling law? The Frank-Starling law states that the more the ventricular muscle cells are stretched, the more forcefully they contract. Sometimes health care providers will elect not to treat conditions such as atrial fibrillation in which there is no functional atrial contraction.

  • What is the Frank Starling law in cardiac hemodynamics?

  • The Frank-Starling Law is the description of cardiac hemodynamics as it relates to myocyte stretch and contractility. The Frank-Starling Law states that the stroke volume of the left ventricle will increase as the left ventricular volume increases due to the myocyte stretch causing a more forceful systolic contraction.
