What is the Frank-Starling Mechanism in Cardiophysiology?
What is the Frank-Starling Mechanism? We will discuss this by talking about the effects of preload, left ventricular stretch and elastic recoil, and changes in stroke volume.

Khan Academy: Preload and Afterload: Frank Starling Mechanism
Carefully follow five different preload scenarios to see how each one will have a different effect on how actin and myosin line up. Rishi is a pediatric infectious disease physician and works at Khan Academy. [14:18]
Khan Academy
Khan Academy: Changing the Pv Loop: Arterial Elastance (Ea) and Afterload
First, learn the difference between arterial elastance (EA) and afterload. Then, understand how EA is affected by changes in afterload, and in turn, how the PV loop can shift. Rishi is a pediatric infectious disease physician and works...
Khan Academy
Khan Academy: Preload and Afterload: Sarcomere Length Tension Relationship
Find out why the length of a sarcomere (in diastole) affects the amount of force that it can generate (in systole), and how that would look on a graph. Rishi is a pediatric infectious disease physician and works at Khan Academy. [8:50]
