An increase in stroke volume in response to an increase in the volume of blood filling the heart ventricle during diastole is ............. law of the heart.
Sterling’s
The Frank–Starling law of the heart (printed here as Sterling’s) states that the greater the volume of blood filling the ventricle during diastole (end-diastolic volume), the more the cardiac muscle fibres are stretched and the more forcefully they contract, so stroke volume increases.
This intrinsic mechanism lets the heart pump out whatever venous return it receives, which is important during exercise. Boyle’s and Charles’ laws relate to gas pressure, volume and temperature, and Newton’s laws relate to motion, not to cardiac filling.
Hence, it is Sterling’s law of the heart.
