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.
What is the Frank-Starling law relationship? Introduction. The Frank-Starling relationship is based on the link between the initial length of myocardial fibers and the force generated by contraction. There is a predictable relationship between the length between sarcomeres and the tension of the muscle fibers.
Why is the Frank-Starling 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 are the 4 Starling forces?
- hydrostatic pressure in the capillary (Pc)
- hydrostatic pressure in the interstitium (Pi)
- oncotic pressure in the capillary (pc )
- oncotic pressure in the interstitium (pi )
