I can honestly say with great confidence that without this video, not once in my entire life would I have thought of my own immuno cells as characters in mad max, speeding across a desert wasteland, slamming an electric guitar with sick riffs while hunting antigens. So thanks for adding that to my existence.

@d33fcon

If schools were like this, I guarantee we would have better educated people around.

Everthing changed when the pathogens attacked

@seansmith4289

I am a PhD student working with cancer immunotherapies and I must say that I loved the last three videos! Definitely laughed out loud multiple times. You brought to life a lot of images that usually only live in my head.  Great job Crash Course team.

So an autoimmune disease is like a civil war inside your body.

@Im-just-Stardust

Hank, you are the most amazing person on earth.

Thx you so much for your efforts and knowledge

I am a junior high school teacher whose main teaching principle is to teach Science in the simplest but fun ways possible. So thankful CrashCourse is here. I always watch their videos and give it a bit of a personal touch before having the everyday battle in classroom teaching. It made such a huge difference. Not only was I able to understand my own field a bit better but students appreciate what they are learning everyday. I am more than grateful to all the people behind this channel. You are one of a kind! Hands down!

@StacySpicyweiner

I would not be half the nursing student I am if it weren't for ALL of these videos. Thank you so much Hank!

@BBBuilds12

The guitar animation was hilarious!

@mandya3105

I LOVE THESE ANIMATIONS SO FUCKING MUCH UGH

@johnlemon1595

Big credit to everyone working on this course. From writing, animation, directing to acting (and all of the other aspects i missed) absolutely awesome job. This course got me interested in going to med school, which i never thought would happen (althouh im still not going to med school :)) Love you guys, keep it up

@floroey

End of an era! It’s making me emotional to watch your last A&P video again. 🥲 i am currently reviewing this before a nursing school lecture on immunodeficiency disorders. I watched ALL of your A&P videos during my pre requisites, and watched them again before I passed my TEAS exam. Thank you for being with me for so many years!! ❤

@TheDeekins

Just wanna say thank you to Hank and the CC team.  I'd been recommended CC many times by friends (since they know I love documentary, Discovery Channel, Nova-style programming) but could never really get into it for some reason.  Hank's lessons on Anatomy and Phil's on Astronomy officially converted me, and I've now got a huge CC backlog to go through.  Thanks for all you do CC team, I just wish I had this (and YouTube) when I was a kid!

@kunal_KB

Thanks alot.. Love from a dedicated Commerce student who is interested in understanding the working of his body ❤
