FOCUS QUESTION

How does the immune system defend the body against pathogens?

The map breaks this topic into its core concepts, connected by labeled relationships. Each link is written so it can be read as a complete statement — not just an unlabeled line between boxes.

Concepts and relationships

  • Immune System includes Innate Immunity.
  • Immune System includes Adaptive Immunity.
  • Immune System uses White Blood Cells.
  • Adaptive Immunity produces Antibodies.
  • Immune System defends against Pathogens.
  • Pathogens display Antigens.
  • Antibodies bind to Antigens.
  • Immune System circulates through Lymphatic System.

How to read this map

Split immunity into innate and adaptive branches, then see how white blood cells and antibodies recognize antigens on pathogens.

Learning objectives

  • Distinguish innate from adaptive immunity.
  • Explain the role of white blood cells and antibodies.
  • Describe how antibodies recognize antigens.
  • Connect the lymphatic system to immune defense.
