The Immune System Explained I - Bacteria Infection

Am 1 Jul 2014 veröffentlicht
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.
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!
You can get the MUSIC of the video here:
Videos, explaining things. Like evolution, time, space, global energy or our existence in this strange universe.
We are a team of designers, journalists and musicians who want to make science look beautiful. Because it is beautiful.

  • “Every second or your life, you are under attack.” Me starts freaking out

  • Watching while sick

  • I miss all my cells that have died in order to protect me

  • im on a game jam right now, and the theme of it fits the purpose of the immunse system, im going to try to make a game on it, i may fail and give up, but lets hope for the best!

  • Hey guys I’m back I turn of restricted mode off

  • Have you ever heard something in science and just wonder; HOW THE FUCK did scientists find this out?

  • This got me to understand why I feel so tired when I get only mildly sick. My body works so hard to keep me mildly sick and not dead that it gets exhausted. Thanks body, I love you.

  • wow i wash my hands everytime i eat and when i finish with work i get soap and water and wash hands

  • Going to show this to my health science teacher

  • Can we get a video for viral infections and autoimmune diseases next please?

  • press 5 for machine, 6 for a newly spawned B-cell, 7 for four types of antibodies (fifth is first)

  • That moment when you watched this then watched Cells at Work and then watch this again XD

  • Can you make cancer stuff

  • That's so cool

  • Hey can you make another one of this and add rest of the cells

  • I’m sick a little right now

  • So, for what I've found online, DE-tvrs can opt to have their videos titles translated, which would be why I see your videos with a Spanish title in my DE-tv home, but your videos are in English. If this is the case, please opt out of that option, because its fucking annoying. Stupid DE-tv. Thanks.

  • Cell: "So... tired... want... sleep. " T Helper Cell: *slaps* " PULL YOURSELF TOGETHER MAN!"

  • I love this! Could you do a video about the science behind autoimmune disorders such as celiac disease and hyperthyroidism?

  • I became 1st honor when i watch thise video can believe it teacher calls me a science boy thank you kurzgesagt

  • At 6:08. Is this why you get a flu shot every year so your immune system is used to knowing how to deal with a flu virus?

    • Fire Wolf57 The flu virus evolves quite quickly, thus the vaccine from the previous year isn’t effective this year. Also the flu virus has a lot of strains that comes up differently each year

  • The beginning where he said all the time we are being attacked I was about to say that sjw will say by oppression
