Starling's law, when applied to the heart, relates systolic pressure to end-diastolic volume. Which of the following statements are CORRECT?

Question

Accepted Answer

the healthy heart works at end-diastolic volumes much lower than the one that produces maximal contractile force

Accepted Answer

in cardiac insufficiency, the activation of the RAAS produces an increase in blood volume which (up to a certain point) tends to improve contractile force by increasing the end-diastolic volume

Answer

an increase in end-diastolic volume is always accompanied by an increase in contraction force

Answer

the increased contractile force produced by the increase in end-diastolic volume does not  increase oxygen consumption by the heart
