How The Immune System ACTUALLY Works – IMMUNE

Sources & further reading:

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

"Its impossible to cover in one video..."
Aww...
"So we'll make a series."
YES!

[Mogawty]

Ah, finally a Kurtgesagt that doesn’t cause existential dread.
5 seconds later: “It’s been a normal day when suddenly, the world explodes.”
On a serious note, this was fascinating. I had a basic understanding of the immune system, but this is so detailed while being fun. Looking forward to the rest of the series.

Me: **gets a minor wound** Oww!
Immune System: On your feet soldiers! This is not a drill! Let's fight this battle with our lives!

"The human immune system is the most complex biological system we know after the human " is a classic example of the human brain humble bragging about the human brain

As someone who studied this in university, it is fantastic to see the wonderful world of microbiology and immunology be portrayed in a format that everyone can enjoy! 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. I'm looking forward to that book :).

[ninaaq]

As a medical student this was really enjoyable to watch and review some of my knowledge from last year. I struggle with ADHD so I have to make every topic interesting to study it well and keep me engaged, these videos were wonderful for me as they made immunology fun and not boring. Thank you!

[marcuskt]

Just want to say I got the book and can't stop reading, never found human biology so interesting. Bought the hardcover and it is an absolutely wonderful read. 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!

Me: im so lonely, why does no one care about me?

Literally trillions of cells inside me: *sire i would end my life for you*

[CountryCowboy]

Because of this, I feel motivated. Inside my body, billions of cells are fighting so hard to keep me alive. They won’t give up for me, so I shouldn’t quit for them 🥰

[Smily_face]

The fact they can explain years of studying into a couple of 10 minute videos show how much they care and how hard they work. It's so well simplified!!!❤️

[kajutokirrito]

Tomorrow is literally my biology exam and I must say I've never had this much fun watching a video about the immune system. Kudos kurzgesagt. You have made me invested in biology.

You never fail to deliver huh?

[SoniasWay]

“It’s been a normal day, when suddenly the earth explodes”

That’s a kurzgesagt video for sure

I JUST FOUND THE BOOK IN A STORE AND AUDIBLY SCREAMED WITH JOY. THANK YOU KURZGESAGT!!

[EternalFlame]

i bought immune on amazon kindle as an e-book and i've read it more than 3 times. It's definitely an interesting book and a beautiful topic. i love the immune system as a topic and it is really fun diving deep into the army that keeps you standing up every day, and sometimes even endangers you in the form of allergies. I would love for there to be a sequel to it, if at all possible. thank you for this amazing book, and i hope you all have good luck on your channel and i hope you are always motivated to keep pumping out new ideas.

Imagine a game where you could play as the immune system of a person, controlling the cells to fight infections as the person grows and ages, and the better you play the longer your person stays alive. And all with Kurzgesagt's art style and music.
Edit: Ok, this blew up. I'm making it! Comment and I'll tag you when I have something playable or if you want to help. I've been dreaming about having a game like that since I was a child and will even put money into making it a reality. I'll try to contact Kurzgesagt about their style too, it would make anything better.
