Dude posted this 10 years ago and saving lives for another few decades
So true
But schools won't take "old" science classes lol
It's amusing how much better you are at teaching this than my bio teacher...
I was essentially think the exact same thing. Lol
Same
same here
Epic117450 dude, that why we're here. 😂
I think ure graduated now =)
Those dislikes are from teachers 👨🏫 who can’t teach like you do 😂😂❤️🤘🏼
Na. It’s because he called the bicuspid valve the mitral valve
I think they are nothing different. So why there are those dislikes?
mitral valve is also called bicuspid valve
@@spiddyman0079the bicuspid valve is also called the mitral valve.
@@kumarsushil3995 but the mitral valve is also called the bicuspid valve
There is no chance my biology teacher would have taught us like this....u r truly amazing sir🙏🏻
I am taking my pre req'd A&P class for my upcoming Paramedic Program. Khan Academy has not only been a staple for my understanding of material for the class, but also for my life. THANK YOU KHAN ACADEMY!!!!
Mad mouse skills, I was impressed by your cleat writing on paint with a mouse lol
He has a stylus.......
Russell Barnes Sssshhhh! Don't ruin the magic!
what stylus?
syberspy9
@@jksbottommole8463 it's a kind of pen, used to write on computers or other screens which supports it.
Just good to understand a normal function of the heart. Better than any teacher at schools.
.... i feel so smart after watching these vids
i was giving up on my revision until i stumbled upon this. thank you for simplifying things down. you're an inspiration. please continue to upload more videos!
Terrific teacher!!!!!!!!!!!!
Love the video! Thankfully the voice wasn't monotonous and he gave a clear explanation.
I absolutely love this video- you explain these concepts quite well; that makes sense why systole is 1/3 cardiac cycle and diastole is 2/3 cardiac cycle :)))
your use of arrows and changing colors makes this SOOOO OOOOOOO wonderful! thank you
Thank you very much you are doing a wonderful job, way better than books, it's not boring and it goes straight to the head. Keep it up you're great!
The fact tt this vid helps students after 9 yrs...
First of all your voice is so clear, your english is fantastic! Second of all, if I could have two first of alls, I would also say that you explain so clearly what my Professor has managed to jumble up. You are now my mentor.....like it or not : )
It's a great video ! It all makes sense now. Thanks a lot for the video.
Thank you Khan after all these years Ive found out exactly where systole and dyastole really sit. Thanks your voice is very clear, your logic is easy to understand. Well done from NZ
Khan academy has helped me tremendously through all of my medical prerequisites!! I am almost finished Anatomy and Physiology 2 and I'm number 1 in my class. I could not have done it without Khan. Thank you!
can I get some help from ya? help an aspiring doctor out here
Something I heard on another video the other day....on how to remember the different heart valves...
All Patients Take Medicine... A, P, T, M.... Aortic, Pulmonary, Tricuspid, Mitral ... :-)
Gud idea
I just want to say thank you so much for all of your wonderful videos!! I am currently a nursing student in my last quarter of school and have utilized many of your videos throughout my program! They have helped me immensely! You guys are amazing and I have and will continue to recommend your videos to many of the first and second year students that are in our program!!
To me,Heart sounds go like PumPum PumPum PumPum

This Man is God sent. Thank You!
Thank you very much for your effort .
Outstanding! Thanks!
BLESS YOU FOR THIS!!!
Actually it's the noise of the valves snapping shut. The blood tries to go back the way it came and forces the valves shut creating the distinct noise. If you're hearing the turbulence in the blood, it's most likely a heart murmur. You can check it out at wikipedia.
a huge thumbs up..thanks a lot!!
you are just amazing. GOD bless you my friend!
So very very clearly taught ! Not too fast and you deliberately take time to explain
Easier to follow
Awesome video. Very helpful.
Shared with my Anatomy/Physiology class (8th period- Cleveland Metro Schools: Lincoln-West International School.
Mark Julius Thanks for sharing. Are there other videos/tutorials you'd like to see on Khan Academy medicine that would be useful for you or your students?

Can you make a video of Systole and Diastole broken down into depth, please? It's one of the most complicated concepts to grasp and this video only touches the surface... For all A&P classes we need to fully understand the valves, sounds, pressures, and volumes and waves of an ECG for each (systole and diastole). Making a video incorporating all of theses would be incredibly helpful to a lot of people...
Blood flow Acronyms I made up to remember them....
Valves: "To Perform My All"

Hope that helps anyone.

It's very specific...The teaching is very high standard and also very clear as I mentioned. :)
Thank you good sir.
Your videos are great and making my life so much easier for a&p 2. A video about a EKG (or ECG) graph would be so helpful!!!
