What is the meaning of Starling law? Definition of Starling’s law
: a statement in physiology: a muscle that is stretched within normal limits at the time of stimulation contracts more strongly than one that is completely relaxed.
Why is Starling’s law important? The functional importance of the Frank-Starling mechanism lies mainly in adapting left to right ventricular output. During upright physical exercise an increase in end-diastolic volume due to the action of the peripheral muscle pump and increased venous tone can assist in enhancing stroke volume.
What 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.
Which best describes Starling’s law of the heart? The Frank–Starling law of the heart indicates that the increased filling pressure of the right heart results in increased cardiac output. Any increase in output of the right heart is quickly communicated to the left heart as an increased filling pressure.
