B) Increases with decreases in TPR
C) Increases its X-intercept with increases in TPR
D) Decreases its X-intercept with increases in TPR
E) Both A and C are true

Question

The slope of the vascular function curve increases with decreases in total peripheral resistance (TPR), as lower TPR allows for greater venous return and cardiac output at a given right atrial pressure.
