Lesson 2

The Innate Immune System

Students learn about the body’s first line of defense—the innate immune system. Using a castle as a model, students explore the barriers of the innate immune system and analyze data from the activity. In an optional concluding activity, students consider specific scenarios that introduce pathogens into the body and assign expected symptoms to components of the innate immune system.

Lesson Questions

  • What are the key features and processes of the innate immune system?
  • How can the innate immune system be modeled?
