Health & Medicine on Khan Academy: No organ quite symbolizes love like the heart. One reason may be that your heart helps you live, by moving ~5 liters (1.3 gallons) of blood through almost 100,000 kilometers (62,000 miles) of blood vessels every single minute! It has to do this all day, everyday, without ever taking a vacation! Now that is true love. Learn about how the heart works, how blood flows through the heart, where the blood goes after it leaves the heart, and what your heart is doing when it makes the sound “Lub Dub.”

I was ten years old when I first found khan academy and I first learnt about the lungs and pulmonary system from there videos and my science teacher was so impressed and now I'm his favourite student after watching more videos
+And Pearl Why is that of any importance to you?
I've been researching into anatomy and found a great resource at Sebs Study Crammer (google it if you're interested)
U lair
Thats great
@sagarkapur9006 helllo how old r u?
Thanks for keeping the "why" at the forefront! I have watched at least 10 videos on this subject and this one is by far the best. thank you thank you!
Thank you. I love you. As said before: "You deserve a noble prize"
I'm am addicted to these videos, I just love to learn!
great video! i studied hemoglobin a lot at a very high level and then watching this video helped connect it all. maybe post a video on hemoglobin and its interaction 2,3- BPG in the blood.
Thank you so much!!! You are the best teacher ever. Your enthusiasm and joy in teaching has no parallel. I am a teacher myself taking the Boards and I have nothing but good words for you. Thanks a million you are the best
Missed my Biochem lecture yesterday and this helped me get back on track, thanks!!!!
It happend to me that ... I've seen this video entirely too... I just wanted to see a little, but it's fully addictive the way this man explain things easily and loving it. It's contagious!
this is soo helpful! THANKS! You know, I've been studying those facts, but this helps to connect the information, to truly understand the mechanism... and not to lose the overview.
I love your enthusiasm! The human body is truly beautiful and wonderful :)
2,3-Bisphosphoglycerate lowers Hemoglobin's binding affinity for O2- molecules which allows O2- molecules to travel to tissue requiring oxygen for anyone wondering why oxygen is removed.
I LOVE all your videos, I owe you my LIFE! lol:) You are amazing, and you have a way of taking really complicated material and breaking it down to be understandable. Wish all teachers knew how to do this:) Keep up the good work and appreciate all videos!!! Ive never seen the "interactive transcript" before that is freakin awesome Im always like, what did he say...and replay it 15 times (which I still do) but that is SO cool. Whenever I have a topic I always look to see if you have a vid on it.
he makes me understand concepts I always tried to understand but never do............best teacher in the whole universe!!!!! 2 thumbs up!!!!! :)
Thanks so much! i comprehend this concept so much more clearer now :D
God bless your amazing soul I get biochemistry now
9:06- " give or take, ive never sat down and counted them" Lol Sal kills me.
Killed me there 😂😂😂😂
This is excellent! I wish the title were more descriptive, because maybe I would have watched it when I needed to! Still a great lesson on the oxygen-hemoglobin dissociation curve and what drives it. Thanks!
It makes sense now, thank you! So much better than the textbook. :D
This is the stuff!!!!! I wish you were my teacher! Im sure alot of educational institutions would absolutely love to have you. Alot of of would benefit having you around...Fantastic!
Still one of the best videos ever .. straight forward and easy to understand
Thank you so much for this educational video. It just helped me pass my exam with an A+, so feel no less than eternally grateful to you. I'll watch all of your stuff closely from now on. Thank you, thank you, thank you.
well...I watched your kidney function video first. This has been the 5th in a row, and honestly, it was better to watch in terms of excitement, brain engagement, and fun than any series or cartoons. :) thanks for these past 1,5 hours!!
You make a difficult topic sound incredibly clear! Thank you.
Ok. Out of all the lectures ive listened on youtube. you have the best voice.
Thank you for the lecture!
I should say you are one of the best lecturer ever.... if you have a published book about hematology, would you post its name please.
I usually get distracted when I sit in a lecture but your lecture is amazing.. I just love it...
Thank you for this incredible video.
Simple, complete, clear, amazing!
excellent teacher. thank you for taking time out of your day to better others futures. I think we need more people like you.
your an inspiration, and your passion is infectious.
omg ! This video deserves a million thumbs up for the clarity, organization, timing, and I love that I could just hear an audio with a clear deep voice and while listening to the voice I am focus on watching all what was written in front of me. I like just hearing an audio with all the step by step instructions or lectures than watching someone visually and them trying to explain everything. This is a well done video and it is perfect for me to watch without distructions what is in front of me but able to learn what this lectures all about! Wow !!! I am so impressed with the voice (calm, confident, knowledgeable , very specific or direct to the point). I could watch or listen your video over and over and over again without getting tired hearing your voice while learning a lot of stuff, because of how you explain things ! Very well done !!! Love it !!!! Thank you !!!! This helps a lot for me !
Sal Khan, you explain it so well! Thank you.
Thank you for this Video.!!
I was confused on this section but from watching this video I actually love the subject on how Hemoglobin works..
:D yay!! thanks again..
All I can say after each video is a big THANK YOU !
Thanks! Currently studying for a big biology exam and your videos are helping me.
you deserve a nobel prize. I love you!!! best teacher ever
Amazing explanation.May Almighty bless you.
This is brilliant thank you for sharing !
this was really helpful, thank you!
awesome vid
I'm M1 student & it really helped me, thanks

I love your videos on LUB DUB and HEART SOUNDS..... I have learned so much from those also... I love everything connected with the heart, blood, and immunity............ Your videos are so interesting and enjoyable... Thank you!!!!
molto utile, riassuntivo ma esauriente, grazie ancora
u did not mention 3rd allosteric inhibitor - bpg and carring on how a fetous gets oxygen from mummy i find it super intresting ;) but to conclude i love the video
This is most impressive. It is not just the great info but the great speaking voice that makes watching this video great. Here's to more of the same.
Really cool! More I learn, more I want learn more and more and more...
brilliant..brilliant explaination sir..,thank u so much for the video
I'm here because I want to educate myself because my son has a rare case of korle bu and I want to understand how the blood works and yeah I'm confused as crap but your video was a ton of help.. thanks
Perfect video thank you. it was very helpful!
Allosteric Inhibition effect of the acidic enviroment is called "Bohr"-effect and it works the other way around too, meaning alkalic enviroment supports the O2-Binding of Haem(Heme).
Anyway, great video as always Sal. You really know how to simplify all these complex knowledge and make it easier to understand without leaving any vital information out. Great Job!
I enjoy learning and studying about human body as that reminds me how amazing creator is my God 💙
hi.This was wonderful!! I totally get it now!!!!! and btw, I was wondering, do you have any lessons on proteins? Meaning, their structure and stuff? Thanks a lot :D
nice and clear, as always, thank you Khan academy :D
Thanks sal it was really helpful
More people need to like his videos, seriously we get what we want and give nothing in return so the least thing we could do is like the videos.
The Creator is indeed an intelligent being!!! I have never seen a mechanism so accurate and well-coordinated as this one!
Tefelo Mathibane creator is also so brilliant that he created Hemoglobinopathies as well...
Simply wonderful group of diseases.
relax. poeing is acceptable
We are fearfully and wonderfully made.... ps. 139
He's beyond an intelligent being He made us talk and made it so we could create cities with the first Jews (Adam and Eve).
Thanks for the video sir! It is very informative and provides a good review of respiratory cell mechanics.
i love khan... i really do... thank you so much.

“I have never sat down and counted them”
Amateur I have spent three decades counting all my cells and I have a number of 54,134 trillion cells.
That means you still have to count more than 10,000,000 cells per second.
i found it brilliant, and you are very brilliant as well.
dudeee i havent seen ya since apcalc bc in high school!! haha nice to see your still around.
having a hard time following because it keeps buffering and dont know how to make it stop. Information is exactly what I need to prepare for my exam
Thank you very much!

I LOVE YOU
YOU"RE A BEAST
THIS HELPED ME SO MUCH
THANK YOU
YEAAAAAAAAAAAAAAAAAAAAAAAAHHHHHHHHHHHHHHHHHHHH!!!!!!!!!!!!!!!!!!!!!!!!!!!!
I learned the concept of allostery from my prof at UC Berkeley, the late Dan Koshland, Sr. Unforgettable, clear, and very intriguing concepts!
thank you as always.
helpful!
awesome!
You really are an absolutely remarkable lecturer. Wouldn't you write a book of teaching principles to share with professors and teachers around the world? I think i would fit well with your social goals, too... because you could (a) use the proceeds to add to Khan Academy or (b) give the proceeds to another agency working towards the equitable distribution of knowledge using technology, etc...
