Obese Chicken I remember when I was a kid, I didn't want to go to school so I pretended to be sick, then I actually ended up with a fever. Placebo effects are weird

Watching this during COVID-19....interesting things to think about during these times.

MAKE A GAME OF THIS PLEASEEEEEE

I had no idea what my prof was talking about when they explained this in class. This helped me so much! May actually pass my midterm now!

Thank you so much for making these amazing videos. I used to watch these when I was taking A&P in undergrad. Now, I rewatch them as a refresher course for Advanced Pathophysiology. Still helpful as ever!

It's pretty funny how I, a 3rd year biomed student, learn 1 or 2 things in these episodes that I didn't learn from my immunology prof. Good job Crash Course, good job.

I am in the library watching this and could not stop smiling :) People around me must think I am procrastinating! Love the animation and how you explain things. Makes learning so much more fun! Thanks heaps.

This and the other Immune System videos are some of the best in the whole A & P series. Great explanations and animations to describe adaptive immune responses to specific germs on a systemic level. Thank you!

You are incredibly awesome. Your videos got me through graduate anatomy and phys 1 and now i'm in part 2! the little cell faces are SO cute and everything you do to put these together are wonderful and soooo beneficial!!

Can't thank you guys .... appreciated n please don't Stop doing this job.... an awesome job ...... thank you

Wow, you make it so easy to understand this complex system. Thank you for saving my grades.

I have to say, i have been struggling with this for 2 days, this video made so much sense. Thank you so much!

thank you guys for this. Thank God for this youtube channel. this has helped me tremendously prepare for my advanced pathophysiology class! you guys make dense information sound so fun!

This is a great series!

Animation was so cute, so accurate and Hank is so charming... LOL I always 'like' these videos before even starting 😙

I have watched dozens of Crash Course videos for the past year. Everything from chemistry psychology and anatomy and physiology. This three-part series on immunity is by far the best. Hysterical and easy to understand thanks for you guys it's time for making memes.

thank you so much! this is uber helpful

Who else wishes there could be some kind of cartoon animation series telling the heroic stories of our bodies' cells battles with germs? These animations are toooooooooooooo cool!!

4:32 Actually not entirely accurate. Activation by T-independent antigens is weaker and does not result (usually) in immunologic memory (in contrast to T-dependent antigens which gives a stronger response, resulting in the development of immunologic memory). But I guess they wanted to keep it simple.

Excellent series! I wish you had a slow motion button so I could slowly absorb all you are saying. I guess just replay over and over works and appreciate this info SO much!

Love this channel. Being a visual, these videos really help.

Helping me so much with my pathophysiology class!!

I REALLY LOVE HOW THIS IS EXPLAINED. SCIENCE IS FUN! KEEP DOING GREAT STUFF. DFTBA!

if you guys make an actual video game like that i will play for sureeee, thank you for these awesome videos.

Wow ... this is the best system Crash Course has covered. VERY easy to comprehend considering how complex the immune system can be. I just emailed this to my anatomy professor. Well done, please keep these kind of videos coming!!

omg, a three part series on the immune system?! my immuno final was yesterday lol Immunology was probably one of the toughest classes I've had to take, along with biochem and cell bio (immunology was the most difficult). I loved the class but hated getting tested on it, just because there are a lot of mechanisms not shown in the video. EITHER WAY yayyy I'm so glad people get to be primed with this video from here on out. This was long over due :D

Cells: I remember *EVERYTHING* Me: I can’t remember for my anatomy test :(

Gonna miss this series, I learned a lot. Thanks so much for all you do Crash Course. Also scrolled down looking for anti-vaxxers, I'll admit it

I love learning, and I love these videos! This is more entertaining than some sitcom.

I love crash course so much. You have taught me to love science and the way you present it is just fantastic.

Lol maple story! That was a game I played a lot once upon a time 😝

The animation and explanations for this video is the best ever. Perfect analogies and clear animations well done crash course :)))

Hank, where is the video on the mammary glands? I thought that they would be covered as part of the reproductive system videos but they are barely mentioned. Why is a defining feature of mammals largely absent from a course on human anatomy and physiology? I can think of reasons but I would prefer to hear your explanation on the matter.

can you please make an episode about vaccines, their advantages and disadvantages .. and give a general idea about the myths like "vaccines cause autism" and so ..!! :D

Not a "myth" anymore. On August 27, 2015 dr. William Thompson who is a senior scientist and epidemiologist at the CDC through a whistleblower attorney released documents stating that the cdc lied about the connection between the MMR vaccine and autism in their 2004 article in the Journal Pediatrics.
