MCAT Basics Podcast

Innate Immune System

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.
