The Immune System Explained I - Bacteria Infection

  • Publicado em 30 Jun 2014
  • 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.

    Crazy to see how far kurzgesagt has come in all these years animation-wise

  • OnceThereWasAUsernameSoLong 🅥

    If you ever feel sad, remember that there's an army of trillions fighting for you every day :)

  • cyberpunkjinx

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

    He teaches us more than science/bio-chem classes can teach in a week within a single video and makes it FUN and INTERESTING while letting us have the free time to do what we want! THIS is a great example of what education systems should be in the future without it taking a toll on our mental health!

    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 ❤

    Very cool to notice Kurzgesagt's animation has gotten better on their vids over the years. It's funny how simplified the animation is on this 7 year old video compared to the one made within the last 4 months I just watched.

    Came back after watching the new video on immune system.

  • Anirban Chatterjee

    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

    I was legit getting so unreasonably emotional during this and I do not know why.

  • Jane Stewart

    This look inside my immune system made me appreciate all it does without my knowledge. I take a lot of it for granted. I'd love to watch a video like this about what effects the food and drink we choose have on our bodies. Junk and good. How is it used, what good and damage it does. It would make me think twice about what fuel (good or bad) I put in my system. Thanks this was great!

    The new version of the video is so much improved. It's good to see your channel grow, in terms of both channel scale and video quality.

    I love the simplicity of this illustration and the simple details to help us understand how complex our bodies are. I am going to do my part to help my “Immune System” by getting enough rest and eating/taking all the necessary foods, vitamins and minerals that help in the battle field!

    You always know that your going to regret knowing these facts, but you cant not listen to them. Kurzgesagt is just too good.

    I cant believe its been 6 years. This was my first video and i definitely got hooked very quickly not only because its flashy but its also complex. Time flies huh, keep it up kurtzgesagt team!

  • 쇼팽쇼팽

    It was a very informative video. The visual images of Kurzgesagt make the information so easy to understand. In addition to information, there is also the pleasure of watching animation. I enjoyed watching good information today.

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