question 194

Multiple Choice

Which of the following statements correctly describes the Frank-Starling law of the heart?

• A)The shorter the initial length of the cardiac muscle fibres prior to contraction, the more forceful will be the subsequent contraction because the fibres are already partially contracted.
• B)Increasing the venous return increases the end-diastolic volume, which leads to an increased stroke volume, so the heart normally pumps out all the blood returned to it.
• C) As cardiac output is reduced, blood pools in the vasculature so that arterial blood pressure increases.
• D) The output of the left side of the heart must always exceed that of the right side of the heart because the right side pumps blood only to the lungs, whereas the left side must pump blood to the rest of the body.
