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? 😂
Reading books are confusing without your helpful videos. You are a life saver!
The world needs more teachers like you

Extremely helpfull for my nurse exam. Among the best educational videos i found on YT.
Just awesome. Huge respect, sir.
so incredibly helpful!
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.
Thanks alot, this was really helpful!
What is really really REALLY interesting !! hahaha he's so passionate about this.
Thank you sooo much khan academy for these amazing videos!! Just loved this one!

Didn't understand this in class at all. Thanks Sal
thank you. soo helpful
THANK YOU !!!! veerrryyy helpful :D
it is so clear now
Really Really good video man! You really explained everything and i've learned alot! Thumbs up!
thank u so much for the video
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 :)
Thanks so much !!!
