CARDIOVASCULAR PHYSIOLOGY

Cardiac Output: Function Curves

vascular function curves, and changes in cardiac contractility affect the cardiac function curve. Changes in total peripheral resistance (TPR) affect both the vascular and cardiac function curves.

Figurę 4.11 Cardiac and Vascular Function Curves

The heart and blood vessels interact wilh each other to detcrmine cardiac output. Depictcd here are a series of vascular and cardiac function curves that illustrate this interaction. Changes in right atrial i pressure affect venous return. Changes in va$cular volume affect the
