    The human immune system is the most complex biological system we know, after the human brain, and yet, most of us never learn how it works. Or what it is. Your immune System consists of hundreds of tiny and two large organs, it has its own transport network spread throughout your body. Every day it makes hundreds of billions of fresh cells.
    It is not some sort of abstract entity. Your immune system is YOU. Your biology protecting you from the billions of microorganisms that want to consume you and from your own perverted cells that turn into cancer. It's so manifold that it is impossible to cover in one video, so we’ll make a series looking at different aspects of it.
    Today, what happens when your body is invaded and your first lines of defenses are engaged in a fight for life and death?

    Ohai! I’m Philipp, the founder and head writer of Kurzgesagt and author of IMMUNE! Let me say a few words about it: IMMUNE is older than Kurzgesagt and I began working on it about a decade ago in university. The idea was to explore a super important but also extremely misunderstood and complicated topic and “translate” it into a language everybody could understand. I’ve done my best to basically write a super long Kurzgesagt video but with less of the limitations of a ten minute video.
    IMMUNE is a fascinating and fun journey through your own body, together 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. A flu or something more serious will not be this abstract thing but something you can sort of witness and imagine which mechanisms are active and which cells are doing what. At least personally, knowing how the immune system works always has given me great comfort when I felt unwell. Also 45 illustrated pages by the Kurzgesagt team make the book very pretty.
    Preorders are incredibly important in the world of books so if you are considering getting it, it would mean a lot if you could do that. Because preorders determine if a publisher will try to get the book into bookstores, so a lot of the book’s success depends on it.
    I’m incredibly grateful that so many of you have watched these videos in the last few years. And I hope you will give my first book a chance too. - Philipp

      The human brain thinks it' the most complex biological system because it has been able to bring humanity to the top of the food chain while the immune system is needed only for when the body is under attack by foreign cells and otherwise doesn't have to do anything, but in fact it's only the third most complex. Ironically, the immune system thinks it's the most complex biological system for the exact same reason, it too is not the first, but only the second.

I'm an engineer I've never found something that explains something so well in an entertaining way to someone like me who knows nothing about medicine. Never wanted to look after myself so much! Great fun read, hoping there will some day be another book? Massive fan of the channel, keep educating people guys!

      Start studying cellular clocks. Imo theyre the most interesting, albeit under-studied, part of human biology. Its also very applicable to the average person, considering the average person sleeps and is exposed to light in a rhythm. Its especially cool considering these clocks play a larger role in muscle rather than the brain which is the opposite of what you’d expect.

Thank you for this beautiful walk through one of the complex systems and fields modern entertainment rarely to never pays attention to in this immense detail. I have the feeling to have understood and learnt so many things that were only cloudy schemes of slight understanding before and probably this book also increases the number of IQ points of every single reader.

      a better term would be 'self destruct" if they stop getting signals to keep fighting they'll eventually self destruct or "die" as its put in the video.. This is so they stop wasting resources once the threat is gone. T-cells would keep signaling to let them know that there's still a threat so they keep fighting. It's not the same way me or you would "die". Macrophages can still die while fighting (I believe that's what is in puss, but I could be wrong)

      hey @Mr Saxman im currently going to study life sciences in uni next year too, i hope to be able to specialise in immunology / infectious diseases and then maybe go on to take a phd in the future. could you give me some advice on the job prospects or how research life is like? also if you could introduce me some universities which offer phd courses for biological science related topics it would be really great. thanks a lot!

In fact, your videos played a big part in me taking this as my career path, and I greatly thank you for it because I absolutely love my field. Your videos are astounding and inspire so many people.
