  • The human immune system may be the most complicated interacting set of organs, cells and chemicals in the body. Working together, these parts perform what often seem like miracles of self-defense. This is the first of three programs on the human immune system. It provides an overview of the parts of the immune system, and describes how they function together as our body's main inner lines of defense against pathogens.

    The material is organized around the following categories:

  • Course Overview
  • Terminology
  • Introduction
  • Anatomy of the Immune System
  • The Innate Immune System
  • The Adaptive Immune System
  • ConclusionPURPOSE/
