Mr. Khan, I've been watching your videos since grade 8... now im in medical school still watching ur videos. Thank you so much for your time and spreading your great talent of teaching to the world
wait what? He been around that long?
John Michael Amen!
John Michael I'm pretty sure you go to my school, haha.
+John Michael me too since high school atleast
+John Michael Haha, I'm in pre-med and watching his videos.
6:35
me during quarantine: ahhh COVID-19
covid is nothing to worry about
I love how excited he is about B cells. You're the best Sal.
I swear I would never understand any concepts taught in my lectures if it weren't for you teaching them in much better depth and explanation
I like to think of opsinization as "honey" that makes the target pathogen more delicious to phagocytes. Visual: bees to honey. "Bee"-cells respond, make honey, to attract "b"ears to eat them.
+Debi Baird hahaha I love it. Great mnemonic!
We had a Greek girl in my med school class that says opsonise comes from a greek word meaning 'to make something tasty'. Haven't forgotten it since!
Haha, Great trick for understanding and memorizing.
That’s a good analogy.
Listening to your explanations is the glue in my studying regimen. Thank you SO MUCH for these videos. I know I'm not only speaking for myself when I say that your videos are life savers.
I go to an elite Australian dental school and haven't gotten any sense of understanding until these videos. THANK YOU!
Elite? Lemme guess Melbourne uni? 😂
I just love how you make everything seem so plain and simple. Thank you.
Reading books are confusing without your helpful videos. You are a life saver!
The world needs more teachers like you

So neatly explained, was looking for good explanation for weeks. Finally!

Great teaching guy! seems more personal when trying to grasp the concepts, nice!
SO GOOD! Don't ever stop making these videos man, you rock! Thanks :D
I don't know why professors have to be so sneaky by omitting info and assuming that we'll somehow figure it out with the hundreds of notes that we have to study. You sound more passionate about what you're teaching than any professor I've known in medicine. Thank you.

+Frank Lia Studying this in undergrad - Molecular and Cellular Bio major.
this helps so much!
Ive been following you for a really long time now... your videos are awesome
man, you're a legend! well explained!
Thank you for this wonderful presentation.
i am wondering about the recognition receptor proteins on the B-cells and helper T-cells.
lessons on immune system often begin with a B-cell receptor proteins recognizing the antigen/foreign particle. But how did that receptor protein get there? You mentioned there are 10^10 possible combinations. So is it just by chance that there will be a receptor protein on some of your B-cells to recognize every kind of antigen out there?
Thanks Khan Academy, for making this video. It's really very helpful.
6:31 Covid-19
This video aged well on that aspect.
يبدو أن التعليقات كلها قبل سنوات فقط انا من الحاضر ...شكرا جزيلا لك اينما كنت و بارك الله فيك❤️على هذا التوضيح الاكثر من رائع
Really enjoy of these videos, he interprets everything so well
I like that he explains the meaning of the words and everything.
Of you just spit out a bunch of names & deliver it in a very dry way, it doesn't get memorized. So it's like he makes a little story for each section of what he is explaining & think that's why his method works so well :)
I listen to this guy teaching while i sleep.
so incredibly helpful!
Thank you! It was long but I FINALLY get it.
the best explanation, thank you,keep the vids coming.
Fantastic! Thank you Mr. Khan!!!!!!
