How the Heart Works animation video

This video combines animation and real footage of the heart to demonstrate how the atrial, pulmonic, mitral, and tricuspid valves of the heart work. The coordinated opening and closing of these valves is what allows the heart to provide blood flow and pressure in one direction, toward the lungs and body.

The Pacemaker of the Heart

Tiny electric currents flow through the heart muscle and cause them to contract, squeezing blood throughout the body. This animation shows the electrical system of the heart and how it is driven by a small patch of tissue called the cardiac pacemaker or sinoatrial node.

Cardiology Medical Animation Reel

This animation shows what angioplasty and stent deployment look like if you could see inside of the blood vessels, up close. There is no narration, but the "balloon" being opened is the angioplasty procedure while the "chicken-wire" cylinder is the stent.
