WOW I am totally fascinated thank you Dr Campbell for this video.

I recently took a course to become an EMT and have been very frustrated with studying the human heart and how it functions,  until I found you on You Tube.  Thank you very much.  Finally, I find that I can easily understand the working of the human heart with ease.

Fantastic. I know nothing about how the body works. But after watching this I now have a good general idea about the heart. I am now going to watch the rest of your videos. This was so good!
