Fighting Infections with Your Immune System
- Understand how several groups of cells in our immune system work together to fight pathogens.
- Develop a model that demonstrates the function of antibodies and memory cells during a primary and secondary immune response.
- Explain how memory cells accelerate an immune response using experimental evidence.
OverviewWhat happens when you get food poisoning or the flu? How does our body fight an infection when we get sick? In this lesson, students will build a model of our immune system to find out how our body responds to invading bacteria or viruses that cause diseases and to investigate the role of memory cells.
