Explain in words and provide a drawing that demonstrates the variable that describes the difference between end systolic volume (ESV) and end diastolic volume (EDV). Your answer needs to be a cardiovascular variable) Ventricles change the amount of stretch based on the amount of blood entering. In this scenario a decrease in blood volume occurs. What is a direct cause of a change in end diastolic volume (end diastolic volume changed, what caused this to occur?). a. Increased contractility b. Decreased contractility c. Decrease venous return d. Increase venous return Explain the physiology taking place: What is the direct effect of a decrease in EDV? (end diastolic volume changed, what happens next?). a. No effect b. Increased contractility c. Decreased contractility d. Decrease venous return e. Increase venous return Explanation: Explain & draw the physiology in the contractile cardiomyocyte taking place lude transporters, ions, gradients, organelles for full credit) What physiological law in this unit describes the changes taking place?

Transcribed Image Text:The heart is a dynamic organ that responds quickly to changes to ensure proper blood flow to the body. The questions below ask you to explain how a decrease in end-
diastolic volume (EDV) affects different variables in the system.
1. Explain in words and provide a drawing that demonstrates the variable that describes the difference between end systolic volume (ESV) and end diastolic volume (EDV).
(Your answer needs to be a cardiovascular variable)
2. Ventricles change the amount of stretch based on the amount of blood entering. In this scenario a decrease in blood volume occurs. What is a direct cause of a change in end
diastolic volume (end diastolic volume changed, what caused this to occur?).
a. Increased contractility
b. Decreased contractility
c. Decrease venous return
d. Increase venous return
Explain the physiology taking place:
3. What is the direct effect of a decrease in EDV? (end diastolic volume changed, what happens next?).
