The Immune System Explained I – Bacteria Infection

Every second of your life you are under attack. Bacteria, viruses, spores and more living stuff wants to enter your body and use its resources for itself. The immune system is a powerful army of cells that fights like a T-Rex on speed and sacrifices itself for your survival. Without it you would die in no time. This sounds simple but the reality is complex, beautiful and just awesome. An animation of the immune system.

Why you are still alive - The immune system explained

Help us caption & translate this video!

[kurzgesagt]

IMMUNE is a fascinating and fun journey through your own body, where we’ll be exploring mystery organs, murder universities, your enemies from viruses, bacteria and cancer (and how your immune system might have killed a cancer cell while you were reading the last few sentences) and the incredibly beautiful and amazing parts, cells and systems that keep you alive. After reading it you should not only gain a new appreciation for your own body but also experience disease differently. Also 45 illustrated pages by the Kurzgesagt team make the book very pretty.

[kurzgesagt]

We are thinking of making an App for tablets out of this video. Would you like that? Did you think the visual system we developed worked? Feedback is much appreciated!

[valerians.]

i cant believe that bacteria would just intrude into my body without my permission. that makes me sick...

[cyberpunkjinx]

Almost 8 years ago, 10 year old me watched this video and loved it.

Now I watch it again, after finishing my immunology unit a year into my biomedical degree, and I think about how much of an impact your videos had on my life. Thank you.

Edit: Wow, two years on! Since this comment I’ve written my dissertation (about stem cells and the immune system!) and am about to begin my masters degree. What a butterfly effect!

[zzvlr]

“Ow! A paper cut..”
Immune system: THIS. MEANS. WAR.

[trashtuber]

This 7-minute video taught me more than school did this year.

[Alistocrat]

"Ill miss you guys"
"Killing stuff was the best part"

Stop giving my body cells personality, you're gonna make me cry.

[AdagioLab]

As a student of Microbiology I thoroughly enjoyed the visual presentation. I have prior knowledge of the mechanism of the human immune system, but this general outline is marvellous because of its utter simplicity.Thank you kurzgesagt

[chrislabedzski]

Wow they literally support each other, and actually fight and plan like a real army, I'm more then impressed

[emmagarciasz]

*“Every second of your life you are under attack”*

Well that’s reassuring.

[caleblim]

I watch this video every time I get sick, just to remember that my body is fighting hard

[AmeVelet]

This was literally what I kept thinking about when I first got hit hard with COVID back in late 2020. Just silently cheering my body on to get the job done and get well soon. Took about a week to be rid of the insane fever/headache but got better thankfully ❤

[ShreyRupani]

I don't know why, but this channel has a unique ability to make me cry...

[WhiteSetsuna]

Avengers had one of the best fight scenes.

Me: Hold my microscope

[SlowYota]

If the cells remember the infection
does that mean they get
like a bacterial vietnam flashback

[oof]

5:09 "I'm dying, leave me alone!"

"I didn't give you permission to die, keep working >:("

[cockatoo]

I'm taking a celular and molecular immunology class this semester.

I cannot understate how good these videos are

[lumengentium]

"Dont die yet, we still need you."
Every teens: This is so deep..

[cooleKinder]

Bacteria: Tries to negotiate with Immune system

Immune system: *peace was never an option*

[halleanjou]

Best educational video I've EVER seen.
