Adam Baum because the education you pay for is a joke. Most people on the internet explain things better then professors to.

Second time around is invariably easier than the first, doh
Knowing something and being able to make others understand this is something totally different ... And you my friend, whoever you are, have a talent in doing this ... Everything in your narration is perfect: from your voice to your drawing and making others remember the knowlege included in your video without having to study it again. So I hope that u are some kind of professor or teacher in a university because you have a talent in that. Friendly greetings from Greece.

Woooowwwwwww my mind is blowwwnnn
You deserve a Nobel prize for how Khan Academy has innovated the educational system. I am about to go to grad school and I have been watching your videos since I was a freshman in my undergrad years. You rock!
you explained it ten minutes what my professor couldn't in 50. thanks.
My professor just started to mention terms like depolarization, repolarization, and action potential without explaining what those meant. WTH?! Thank you for simplifying the concept behind the terms. Most of us learning this are undergrads LoL maybe some professors forget this and start throwing medical jargon at us like we already know what they mean.

Wut???? We learnt these terms in high school, and my university doesn't accept students who are unfamiliar with such basic terms. Interesting

Really the first professor to explain action potential properly was in my first year of med school. Actually a lot of topics my undergrad just told us to accept w/o explanation were covered cause I ACTUALLY HAVE TO UNDERSTAND THIS TO KNOW IT. cough still annoyed at undergrad.
Watching this as a preface to my cardiopulmonary block of med school. :D Good old khanacademy. Best free MCAT prep out there.
I have watched probably 10 different videos on this and after this one, I finally get it. You're amazing. Thanks for all you do!!!
There are so many classes I wouldn't have passed if it weren't for Sal. He got me through 2 math classes, chemistry and now physiology. Can't thank him enough!
I am extremely impressed. You have an amazing talent for teaching!
I wish my anatomy and physiology teacher taught like you make it so easy to understand!

amazing fast easy lectures that makes you understand everything with pure simplicity WOW!!!!!
I show these videos to my Surgical Technology students every time I teach them the heart. I love these! Thank you so much!
Usually, Khan lectures are a little drawn out and the person just mumbles and takes a while to get to the point. This was perfect for me. Right into it, no delays and beautifully explained. Loved it
This video is soooo helpful just as the others I"ve watched by you! Thank you for your time and effort in this presentation. I now understand!
Struggled with this for soo long! Thank you for the video!! Dont know why I wasted a hour looking at the book when I could've just watched this video. Thanks again! :)
Salute. Beautiful explanation and I can easily understand the Heart and how it functions now. Keep uploading brilliant videos like these.
In school to become and EMT and reading the section about depolarization and repolarization was like trying to learn a foreign language. No reference pictures or anything visual for me to connect the dots. Thanks for the explanation and pulling back the clouds of confusion for me. It all makes sense now!!
Fantastic. I've never imagine it could be so easy to understand !!
Your voice is soothing, you got that voice tonality down. Also you explained so easily compared to my textbook. Great job!
WOW!! That is one hell of a GREAT explanation! You did wonderful! Thank you
I sincerely hope you teach..somewhere...this is fabulous!
Hahahahah. You're not the only one brother. It's gentle and relaxing. Perfect for learning!
I watched this video a few times. You did an excellent job! Thank you.
Excellent video and flawless explanation! Thanks for sharing!

Hi Rishi, I just want to thank you for all your great videos. I am starting Nursing school, and I needed to review some of my A & P. I am a total visual learner so your videos make perfect sense. Could you do a video on EKG my book is confusing me.
That was a better explanation than my text book. Thank you!
Khan you're perfect teacher👩🏫
This is a great presentation. I love the analogy of highways too, thank you.
OMG! You're videos helped me so much for my IB Biology Exam 😍👌🏻
This was the best step-by-step of the conduction system! It really made it clear for me!
AWESOME VIDEO. you explained in 10 mi s what my professor couldn't in 1 hour. BRAVO!!
You sir deserve a cookie
I wish our anatomy teacher would teach directly from videos like this one!
You Sir. Are a gifted teacher!
