Immune System, Part 3: Crash Course Anatomy & Physiology #47

THE FINAL SHOWDOWN! This is the last episode on the immune system and also the very last episode of Crash Course Anatomy & Physiology. In it, Hank explains how the cellular immune response uses helper, cytotoxic, and regulatory T cells to attack body cells compromised by pathogens. He also explores how cytokines activate B and T cells, and what happens if your immune system goes rogue and starts causing autoimmune trouble.

So thanks for adding that to my existence.

    +92tpeter Yes! There are also some diseases that are not strictly autoimmune, but wouldn't be that bad for you if it weren't for your immune system. Take Hepatitis B for example, there's a reason why children that were infected when they were infants become effectively immune to the disease, and that's the fact that the virus infected cells are seen as normal tissue cells by the developing immune system, since they were presenting their various virus bits from the start. The infection itself doesn't cause serious enough harm to be noticeable, it's the immune response that basically turns your liver into Omaha beach.

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!

    Ya'll need a crash course microbiology! I'm wrapping up my micro class now (finals week...terrified) and these 3 immune system videos have helped so much! I've been taught so many small details in micro, but honestly haven't been able to see the big picture; the class sucks. So many students have trouble when it comes to this class and we don't have tutors for it because it's an upper level science class (in my college anyway). Help us! It would be a bit late for me, but at least I'd learn something after the fact!

"I'm not making some sorta....CRAZY FINGER NECKLACE or somethin'." I always thought the writing on that mod was amazing and it really brought me some great nostalgia feels.

    +Megan Rivera The Someguy series in general is awesome. He also made that one companion that I still can't use because it requires an expansion pack that I don't have and don't want to buy just because of that, and yes, that is still pissing me off... =p Why can't mod creators make their own damn bulletproof vests? XD

    I think this kind of content deserves much more attention and recognition , other than helping with tests , its truly sparks a desire to learn more because it is so well written and so professional while the animation are dead on perfect. I cant say it enough how much I am thankful for crash course for inspiring to learn more , maybe I finished this playlist , but on my way for all the rest ! thank you !

    on one hand I'm glad these videos exist. on the other, it pisses me off that I have to spend this much time studying the videos because our teacher doesn't actually teach us nornally on lessons but expects us to know this anyway
