In the first part of a multi-video series on how the human immune system works, Kurzgesagt describes how the system’s first lines of defense work when your body is invaded by microorganisms.
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.
Kurzgesagt founder Philipp Dettmer is publishing a companion book to the series, Immune: A Journey Into the Mysterious System That Keeps You Alive; it’s out in late September.
I have read a lot about the human immune system over the past 18 months, but this video was still helpful in understanding how it all fits together. For more information, consult their extensive list of sources or watch their earlier video on what the SARS-CoV-2 virus does to a human body.
