The Immune System: Innate Defenses and Adaptive Defenses

There are so many critters out there, bacteria and viruses that want to wreak havoc in our bodies. How do we defend ourselves against such tiny threats? The immune system! This is quite possibly the most profoundly remarkable aspect of the human body. It almost defies comprehension, the resourcefulness and efficiency of this system. An in-depth analysis will require an entire separate immunology course which will come in the future, let's just get our feet wet for the moment!

Check out "Is This Wi-Fi Organic?", my book on disarming pseudoscience!

It never ceases to amaze me how complex this collaborating community of cells, we've inherited through birth, is.
Thank you for sharing this information.

My age might exceed the ages of some of your viewers, but I still find these videos to be interesting; I enjoy learning about most things and often listen to these videos while performing other tasks.

I cannot believe that you were providing this information completely free of charge… This is gold… I do not believe in conventional education… That is to say, I do not believe in going to a classroom to learn about things… We homeschool our children and that’s the way it’s going to be… This is great schooling right at home

I love your videos but it's been a few years since I had to watch your videos but now I have to redo a module from 2 years back and I just got like PTSD flashbacks when your song came up. Remembering me like completely sleep-deprived desperately trying to use your videos to save my ass before a test (and it helped soooo much)!! Now a few years later I can't even sleep less than 6 hours, nevermind pulling allnighters for almost 2 days D: I just want to be done with Uni omw
