According to the Frank-Starling mechanism of the heart,

Question

Quizplus · Accepted Answer

The Frank-Starling mechanism states that stroke volume (the amount of blood ejected by each ventricle with each contraction) increases with increased venous return (the amount of blood returning to the heart from the veins). This is due to the fact that increased venous return leads to greater stretch of the ventricles, which improves their contractility and therefore the amount of blood they can pump out with each beat. Choices A, B, and C are incorrect because they do not accurately describe the Frank-Starling mechanism. Choice E is also incorrect, as the ventricles do not contract simultaneously - the right ventricle contracts slightly before the left ventricle to ensure proper blood flow through the pulmonary circulation.
