The mechanism that ensures the volume of blood discharged from the heart is equal to the volume entering its chambers is ______ law of the heart.
A)Boyle's
B)Frank-Starling's
C)Dalton's
D)Newton's

Question

Quizplus · Accepted Answer

The mechanism described in the question is Frank-Starling's law of the heart, which states that the volume of blood ejected by the heart is directly proportional to the volume of blood that enters its chambers (ventricles), ensuring that the amount of blood leaving the heart is equal to the amount entering it. Boyle's law relates to the pressure and volume of gases, Dalton's law relates to the partial pressures of gases in a mixture, and Newton's laws relate to motion and forces.
