Educator Edmond Hui teams up with animator Anton Bogaty to explain the often misunderstood inner-workings of the human heart in this animated lesson from non-profit TED-Ed.
There's a lot of misunderstanding about the heart. Information like this used to be solely for medical students, but now anyone who wishes can watch videos such as this and know more about the human heart than the best physicians of 200 years ago.
From the youtube page:
For most of history, scientists weren't quite sure why our hearts were beating or even what purpose they served. Eventually, we realized that these thumping organs serve the vital task of pumping clean blood throughout the body. But how? Edmond Hui investigates how it all works by taking a closer look at the heart's highly efficient ventricle system.
