In this pre-class lecture, we'll be going over the physical and chemical barriers of innate immunity. In class on Monday, we'll learn more about the cellular components in detail.

 

After we finish on Monday, it might help you to take a look at this youtube video again (posted in your study guide) as well as other videos to really get the details solid in your brains before we move on to the adaptive immunity. 

 

MY BIGGEST advice with the immune system is review review review. Make sure you stay on top of your studying here because it is going to get really detailed really quicky. Most of it isn't super complicated like some of the other materials we have covered, but is a LOT of details that you need to keep organized in your brain and that's what makes it hard.
