Watch how the heart works (Video)

Here a very informative video on how the heart works.

Your heart is probably one of the most hard working organs in your body. It never stops, does not rest and is responsible for sending fresh, oxygenated blood to every cell in your body. Made entirely of involuntary muscles (muscles that work without your specific instructions), the heart is a bundle of strong muscles that are capable of working endlessly. But, have you ever wondered how this amazing organ works? Well, in this video you will learn exactly how your heart receives blood, sends it to your lungs for oxygenation and then distributes it to the rest of your body.
