Summary

The immune system is split up into two main categories - the adaptive immune system and the innate immune system.

This episode will cover the intricacies of the innate immune system beginning with an overview of its constituent cells. We will then explore three pivotal elements of the system: anatomical barriers, the general inflammatory response, and the complement system. This will show up in the bio/biochem section of the MCAT.

For additional reading on this topic, you can refer to the NIH’s Innate Immune System paper.

0:00.0	Welcome to MCAT Basics, your ultimate guide to the essential topics you need to master for the MCAT,
0:07.0	brought to you by the physicians at Med School Coach.
0:10.0	Every week, Sam Smith breaks down high-yield MCAT topics, ensuring you're primed for success on test day.
0:16.0	Join Sam as we explore the most crucial subjects outlined by the AAMC, pulled from official
0:21.7	practice materials and third-party resources.
0:24.5	Get ready to elevate your MCAT game with topics tailored to maximize your score potential.
0:31.5	Hello, I'm Sam Smith.
0:33.5	This podcast is going to cover the immune system, and the immune system really breaks down into two main categories.
0:40.3	That is the adaptive immune system and the innate immune system.
0:44.0	I'm splitting that up.
0:45.2	And therefore, this podcast is going to be on the innate immune system.
0:49.5	I'm going to start by introducing the cells of the innate immune system.
0:53.2	And then I'll go through kind of the different layers of the innate immune system, break each of those down,
0:58.7	I'll spend quite a bit of time discussing the inflammatory response, and this material is going
1:03.5	to show up in one out of the four sections mostly, which is going to be the bio-biocem
1:09.1	section where you'll see a lot of these different
1:11.3	physiological systems. And like a lot of these different podcasts, this is kind of a surface-level
1:17.0	view of the innate immune system. Like an onion, you could just keep peeling back these layers
1:22.0	and get deeper and deeper and deeper and deeper into the immune system. This, of course,
1:25.7	is just meant to really cover what you could see on the MCAP.
1:29.2	So with that said, let's get into the innate immune system.
1:39.4	So as I said in the intro, the immune system really breaks down in two main categories. That is the
