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

Question

Frank-Starling's law states that within physiological limits, the force with which the heart contracts and the volume of blood it pumps out is proportional to the volume of blood that enters its chambers. This ensures that the volume of blood discharged from the heart is equal to the volume entering its chambers. Boyle's law relates to the pressure-volume relationship of gases, Dalton's law relates to the partial pressures of gases in a mixture, and Newton's laws of motion relate to the behavior of objects in motion.
