Isovolumetric Contraction
In this video, I talk about the isovolumetric contraction of the ventricles. Once the signal travels to the ventricles, the ventricles contract. However, the valves remain closed until the pressure builds up high enough to open those...

Khan Academy: Pressure Volume Loops: Why Doesn't the Heart Rip?
Understand LaPlace's law to see the effect that pressure, radius, and wall thickness each have on the "wall stress" in the left ventricle to answer the question of why the heart never gets a rip or tear. Rishi is a pediatric infectious...

Khan Academy: Heart Introduction: Lub Dub
Ever wonder why the heart sounds the way that it does? Opening and closing of heart valves makes the heart rhythm come alive with its lub dub beats. Rishi is a pediatric infectious disease physician and works at Khan Academy. [9:50]
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]
