The Heart, part 2 - Heart Throbs: Crash Course A&P
Today we're talking the heart and heart throbs -- both literal and those of the televised variety. Hank explains how your heart's pacemaker cells use leaky membranes to generate their own action potentials, and how the resulting...

The Heart, part 1 - Under Pressure: Crash Course A&P
Your heart gets a lot of attention from poets, songwriters, and storytellers, but today Hank's gonna tell you how it really works. The heart's ventricles, atria, and valves create a pump that maintains both high and low pressure to...

The Cardiac Cycle Phase 1 - Atrial Systole Made EASY!!
The first phase of the Cardiac Cycle is Atrial Systole. In this phase, we see a number of things happening. We take a look at the P wave of the electrocardiogram, the pressure changes in the atria and ventricles, as well as the volume of...

The Cardiac Cycle Phase 2 - Isovolumetric Ventricular Contraction
The cardiac cycle looks at all of the things that happen from the beginning of one heartbeat to the beginning of another. Phase 2 of the cardiac cycle is called Isovolumetric Ventricular Contraction. We cover the QRS complex of the EKG,...

How Blood Flows Through the Heart
In this video, I go through the process of how blood flows through the heart. It shows blood entering via the vena cave to the Right atrium, then getting pumped into the right ventricle, to the pulmonary vein to the lungs, to the left...

Action Potentials and Contraction in Cardiac Muscle Cells
In this episode, I show how the Action potential is generated in cardiac muscle cells and how this results in Contraction of the Heart. When the action potential happens, calcium ions are released from the Sarcoplasmic reticulum, causing...

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...
