How does the heart pump blood? – TED Ed

Watch more with these video collections:

“For most of history, humans had no idea what purpose the heart served… although everyone could feel their own heart beating, it wasn’t always clear what each thump was achieving… Even in the 21st century, only a few people in surgery teams have actually seen a working heart.”

How the heart actually pumps blood, a TED Ed by Edmond Hui, with animation by Anton Bogaty.
