Question

Quizplus · Accepted Answer

A) Contractility: This refers to the heart muscle's ability to contract and pump out blood. The stronger the contractility, the larger the stroke volume.
D) Preload: This refers to the amount of blood that fills the heart's chambers before it contracts. The more blood that fills the heart, the larger the stroke volume.
E) Afterload: This refers to the resistance that the heart has to overcome to pump blood out of the heart and into the arteries. The higher the afterload, the lower the stroke volume.
