Immunity refers to the body’s ability to defend itself against disease and infection. Immunity can be categorized into two different forms: innate or adaptive. We will explore these two types of immunity in detail. Have you ever wondered what infections look like from the pathogen’s perspective? If our immune systems are so effective, why do we still get sick? The immune system is a complex network of cells and tissues that work together to protect the body from infection.
In this simulation, you will take on the role of a pathogen attempting to establish an infection in a human body. You will encounter the major cells and organs of the immune system as they work to eliminate you. Through this interactive experience, you will gain a better understanding of how immune cells destroy invading pathogens. By examining historical data maps, you will also learn how an individual’s immunological status influences both personal health and the spread of disease in their community. Additionally, you will meet the key cells involved in immune memory and explore the role of immunization in preventing diseases. This simulation will prepare you for a global health investigation challenge.

Innate immunity | Adaptive immunity | IgG | IgM | IgA | IgE | Thymus |
First line of defense; does not have memory components, and does not change when it encounters an infected cell. Involves macrophages and NK cells. | Appears when someone has received a vaccine or has been exposed to a virus; involved in adaptive immune response. | Produced when fighting off an active infection. | Appears during an active infection. | Found in mucosal areas such as the gut and respiratory tract, provides protection against pathogens. | Involved in allergic reactions when the body encounters allergens. | Where T-cells mature. |
What is the primary mode by which a macrophage engulfs pathogens?
Phagocytosis.
What is a major functional difference between B cells and T cells?
B cells are involved in antibody-mediated immunity, while T cells are involved in cell-mediated immunity.
Identify two methods of immune evasion by pathogens:
Pathogens evade the immune system through antigenic variation and latency.
