repetition is the best way to learn. I enjoyed this video, thank you.
+myra B Actually, the best way to learn varies from person to person. It may work for you, but for most people the best way to learn is to actively question and understand the concept. If you are trying to learn facts, then yes, repetition is good. :)
You are a legend, I cant believe you explained this concept better in 20 minutes than my lecturers could in 3 hours. :D Love it keep the good work up man. Thank you very very much.
Dude please give a lecture about advanced immunology - B and TCR formation, complement system, cytokines, etc. I am studying medicine and you normally have enough substance to achieve greater levels of education but the immunology is under-developed :(
I feel you, dude
duuuuuuuude
My dude I understand what you're saying, digging up advanced immunology information on the internet isn't easy, dude.
What can i say except you're welcome ruclips.net/video/LSYED-7riNY/видео.html
Miguel Sampaio Peliteiro dude thanks for the warning man
i love your existence KHAN! YOU ARE THE MOST AMAZING TEACHER IN THE WORLD ! Thank you for everything you have done for us college students !!!!
This is why I decided to donate, while it is only $5 a month, together we can make sure his platform is here for everyone. Even my 3rd grader learns from him!!!
"hey i found this shady thing floating around" love the way you make difficult material enjoyable to understand
i had an incredible professor for my immunology course, who happens to be one of the top faculties in my university. Your lecture on the Helper T cells was perfect. I never thought that I could compare anybody to my immunology professor, but you are just as good. You have talent for teaching that very few people have and this is why you are so successful.
Great video! this isn't easy to understand, I enjoy the redundant information since introducing this subject once into the mind doesn't cut it. Keep up the videos!
"I found this thing, i killed it, here's a part of it"
"this guy, andthis guy, actually do stuff".
words i understand, perfect :)
thank you x
I am a Ph.D. student in Biochemistry/Molecular Cancer Biology, recently checking some interesting vids here specifically for interferon-gamma/cytokines induced immunity invasion which triggered tumorigenesis and happens to run into your video, very neat and easily illustrated (since immunology is not my background lol) keep up the great work and probably will check out more later!
Exam tomorrow, love from New Zealand buddy, you have saved me at least 3x this year. Many thanks
This video is going to allow me to get a A++ on my microbiology test tomorrow...thank you!!! GOD BLESS YOU!!!!
It was like a movie,, love the ending though.
Thank u so much , 3 hours ago I didnt know a thing in immunity,,
You're a life saver! My biology teacher sucks and I have my biology finals tomorrow! But thank God for someone like you! :D One of the best ways to help people, I swear! :)
all of your videos related to the immune system are simply the best. you covered everything that my book talked about, and it all comprehensive and intereseting.
thanks for your knowledge and motivation!
Nice video, especially for beginners. However, It can also help you gloss over your knowledge for more advanced viewers too! Congrats for your efforts and keep up!
7:36 - Beginning of what a Helper - T cell is.
Thank you it was so helpful I have a biology test tomorrow! I hate high school 🤦🏻♀️
Thank you so much! I actually understand this stuff now. I appreciate your time with this. You ROCK!
you are amazing. Thank you so much for taking the time out to help us mere mortals.
really hope somewhere out there you are getting the credit that you truly deserve. again thank you.
after searching all over the internet for a good explanation about this subject, in english and portuguese(my first language), I could FINALLY understand!!! Thank you so much!
Thanks you so much - you explain difficult topics in way which that makes them so much clearer :)
I would not get through undergrad health science without your channel! Thank you so much!!!
love these
he is better than my teacher
you know I watch any of your videos for detail understading for my pathophysiology class and it helps me a lot!! and trust me you have the most amazing voice that anyone can never get bored listening
!!
Dude i wish my professors were as good as you. And i am a medicine student. you rock.
You have no idea how much these videos help me! Love your work :)
All I can say is thank god I have found your video's, my preferred learning style is not reading from a text book, I don't take anything in!!!! but now I understand what I am learning. Thank you
This is so helpful! Thank you! I FINALLY UNDERSTAND!!!
I really appreciate your videos, they're really helping me a lot.. I'm a 1st year medical student
I love you so much. I have two days until my final, and I'm finally starting to understand this. All because of you, as always
Thank you for the videos! I am learning a ton of stuff, this explains better than my college because you show pictures and actually explain it! I LOVE IT LOVE IT LOVE IT THANKS A TON XOXO KHAN ACADEMY
Thank you soooo much for this video!! I've read this like three times in my immune book and it finally made sense when I watched this video :)
better than how my bio teacher explains this. THANK U SO MUCH YOU ARE A LIFE SAVER. YOU REVIVED MY SUFFERING GRADES
these videos are amazing i have an exam in a couple days and these videos are better than lecture notes and my lecturer.
THank you for putting these up
"I found this thing, I killed it. Here's a part of it." Hah, get it man.
The teacher is amazing! And the videos are so helpful.Thank you so much for making such videos! :)
I literally did not understand B and T cells at all under until i stumbled upon your video. Thank you so much!
Thank you for your precious Video!
Perfect speed, allowed me to make notes while watching the video!
I wish u were my micro teacher! I cant understand his lectures, but then after watching ur videos everything makes sense! thanks so much!
There are a lot more details I need to know, but these videos have really put the big picture together for me.
This is great !
I don't normally like or leave reviews on youtube ! But thank you soooo much !! You r are GREAT!
Your videos make more sense than my lectures :) .. Now I am confident with my test on Wednesday. Thank you !!!
haha i love how he put fun into biology makes me to remember things even better.
"this guy and this guy actually do stuff " hahaaha
You did an excellent job. We need mroe instructors like you. Thank you.
mysterious n amazing way our body is created! and always great teaching from Sal, big thanx^^
Thank you so such for all this work. My daughter is lucky she can understand English, because her classes in our country (France) are so badly taught -not all but this year the biology one is particularly bad- that she learns things on RUclips. The difference between these cells was so poorly explained that she was all confused and now she's fine.
French pedagogy is tough to survive.
your videos are a blessing.. thank you so much...
Great. It has finally cleared it out for me. so much interesting than the boring lectures in my university. I hope that there will be more lecturers like you!
Big Big Thanks for those videos, such interesting topic presented in available and understandable way. Amazing!
Wow that safety mechanism is beautiful. Hard to believe the evolution created all of this. Yet it did! Amazing!
Thanks for the video. it's highly educating. It can be used in a virtual laboratory.
Absolutely godsent video, you have answered all my questions
I've watched a few of your vids and based on the comments, I think you may be the most liked man on the internet
watch in speed 1.25 and its bearable,
great information, way too slow and repetitive
some of us like the repetition. helps us remember it better
yeah i get that, i just find it annoying (:
OMG thank you. Genuinely found this so helpful XD
how do you change the speed?
go to the settings bit where you can chose the definition and there is a speed option above the definition option
Thiscmakes for a great recap on my study. Thanks!
@khanacademy bless you for doing these videos.people these days dont like sharing knowledge.
this videos makes .... studies .. amazing ...and interesting
OMG This is awesome! Just what I needed!!! Thanks :)
Thank you! Thank you! Thank you!
I am finally starting to understand!!
I could open-mouth kiss you right now.
you guys are amazing! i leanred soooo much for my yr 12 final exams :D
you explain this SO much better then my lecture! she started going on about how t cells are like university student in that only some of them pass the test.....
Your videos rock!!! Thanks for the great info!!
this is the best vid about immune system on the web.
is there anything you are not good at!? you're amazing!!!! thanks!
I found this video when I was taking A & P II and it was a life saver!! Now I am taking micro and I referred back to your video for a refresher on immunity!! You are the best!!
You still around today?
hey, thanks so much! your videos are so helpful.. im studying now and listening to your video at the same time! its so helpful ^^
I can't thank you enough for saving my life!!!!!
Thank you for clarifying my AS biology topic!
Best video ever!! Thank you so much!!!
Yes. I read from my textbook that there are two types of helper T cells. One that activates B-cells into plasma cells, and the other that activates cytotoxic t cells.
Very helpful, thank you!
i'm liking every video in this series. awesome!
these are awesome. thanks so much! so much better than my text book.
half a million views in 5 years. Taylor Swift gets that many in 5 days. Imagine if it were the other way around.
+fleshcookie I know, it ought to be the other way round!
+fleshcookie people like to waste tym rather than studying
because studying is boring
It is because stupidness is the easiest to achieve!
dude............. taylor swift song is like usually 3mins long and this video explains a hard concept in 20mins..... and not everyone on earth studies pharmacy/medicine/genetics...
You take the lame out of bio. Watching an animation that resembles Space Invaders helps me learn. Thank you so much for making the world smarter!
Good. Could you do a video about a special immune reaction: autoimmune diseases?!
Thanks.
thank you Sal youre the best.
very helpful review, thank you Khan Academy
Very IN DEPTH!
Helped so much, thank you so much!
Thank you for doing this, I love Khan Academy!!!
I just wanted to let you know that I think you said or insinuated that the B-cell phagocytosed the pathogen and then presented it on the MHCII molecule. However, I don't think B-cells ever phagocytose and kill microbes.
Either way this video was very helpful. Thank you!!
Thanks, this video is perfect for revision, so awesome
great way to teach about T and B cells! my teacher made it so confusing!
OMG. This is such an awesome video. Thank you
wow this helped a lot thanks!
Great lecture. Thank you!
Thank you, perfect!
Haha! Got this this on one on my 3 questions for oral exam in histology! This really helped me;D Thanks for posting!
your vids are amazing! thanks!!
Thanx Bro, a lot better than the prof I have here.
Dear @khanacademy, thankyou for always being my helper t cell
