Which of these would cause stroke volume to increase? A)when venous return is increased B)when venous return is decreased C)when diastolic blood pressure is decreased D)both when venous return is increased and when diastolic blood pressure is decreased E)both when venous return is decreased and when diastolic blood pressure is decreased

Question

Quizplus · Accepted Answer

Stroke volume increases with increased venous return because more blood is returned to the heart, allowing it to pump more blood per beat. Decreased diastolic blood pressure can also lead to an increase in stroke volume, as it reduces the resistance the heart must overcome to eject blood, thus potentially increasing the volume of blood ejected.
