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.

You can now preorder the Kurzgesagt Immune System book! “IMMUNE - A Journey into the Mysterious System That Keeps You Alive”: kgs.link/ImmuneBook 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.

I would think that if we had more teachers who are more motivated to teach, we could have a much more knowledgeable and more progressive society. But, a big factor in that is if they get the money for it. I would love to be a teacher but I would most likely have to burn myself out with another or 2 extra jobs to pay my bills and get what I need to survive. My chemistry and environmental science teacher in HS spent his own money to purchase better materials and books for us. He's one of my inspirations to continue learning.

@RainAngel111 2 года назад

I noticed that they eliminated the simplified immune cells in the newer immune videos. I think that's partially because they have a higher animation budget now, but I also think they realized that the simplifications in this case actually made things worse. Now in addition to remembering the different cell types and their interactions, you have to remember which color matches which role, and which plain coloured circle is which. I find the newer immune cells easier to remember. It's like they're each a character with a unique design and personality, which is much easier to catch onto.

Γιαννης Θεοδωριδης I'm not sure how severe your infection is, but try putting some Neosporin in the wound and cover with bandage. Do this for a couple days. If you dont see improvement, you should see a doctor ASAP - you may need antibiotics (no biggie, just drink a small amount for as many days as you're told,like taking medicine) :)

To be honest chances are you don't believe in God or are an awful sinner this is why depression enzymes gets activated... They literally want you to change or If you don't cz you're so arrogant they don't want your soul in this pure body. Maybe you should just ignore me I'm a peasant in the comment section anyway so who cares about what I say. Doctors know better right? Go to therapist they say.. but in 2020 therapists are more depressed than patients. Take my advice and call it natural selection OR laugh at me and call me crazy... Nobody really cares anymore
