Write what each word means, using the article.

Do not copy the article. Write two things you learned, the way you would explain them to a friend.

Answers below are taken from the article’s stored facts, so they match what the student read.

1. What is the cellular mediators?B lymphocytes (producing antibodies) and T lymphocytes (cytotoxic, helper, regulatory)
2. What is the clinical relevance?Underpins vaccination strategies and is implicated in allergic and autoimmune diseases
3. What are the super secret agents in my body?The super secret agents are special white blood cells called lymphocytes. Two main types are B cells, which make antibodies, and T cells, which help B cells and can kill infected cells.
4. How do these agents remember bad guys?When the body first meets a germ, some B and T cells become long‑lasting memory cells. They remember the germ’s shape, so if the same germ comes again, the body can fight it faster and stronger.

Immunological Memory: The capacity of the adaptive immune system to mount a faster and stronger response upon re-exposure to a specific pathogen.
Humoral Immunity: Immune response mediated by antibodies produced by B cells, primarily targeting extracellular pathogens.
Cell-Mediated Immunity: Immune response involving T cells, which directly attack infected cells or regulate immune responses.
Antigen Presentation: The process by which immune cells display antigens to T cells, initiating an adaptive immune response.
