Question

multiple choice question what is the frank - starling law of the heart? the greater the venous return, the greater the blood pressure. the greater the peripheral resistance the greater the blood pressure. the greater the stroke volume, the greater the cardiac output. the greater the preload, the greater the force of ventricular contraction.

Explanation:

The Frank - Starling law states that within physiological limits, the greater the preload (end - diastolic volume), the greater the force of ventricular contraction due to the optimal alignment of actin and myosin filaments in cardiac muscle cells.

Answer:

The greater the preload, the greater the force of ventricular contraction.
