Why Heart Cancer Is So Rare It (Almost) Never Happens
The heart is practically immune to getting cancer. 2 in 100,000 of those who have cancer are those with a primary cancer of the heart. That is an astonishing low number. So, what is so special about the heart that it rarely, if ever,...

The Circulatory System Part 1: The Heart
The heart! What a symbol of love and affection. But does emotional processing really take place in the heart? Sorry romantics, but no. That's the brain's business. But the heart is still miraculous. It is a completely natural pump whose...

The Pacemaker Potential of the SA Node and the AV Node
In this episode, I talk about how the Pacemaker Potential results in the signal that causes the heart to beat. I show how the greater conductance for Sodium ions in the Pacemaker Cells in the S.A. Node cause the cells to depolarize,...

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...
