What is the function of the lymphatic system in immunity?
✔✔ The lymphatic system helps to transport lymph, a fluid containing immune cells, throughout
the body to fight infections.
How do B cells contribute to the immune response?
✔✔ B cells produce antibodies that bind to specific antigens, marking them for destruction by
other immune cells.
What are the primary components of the innate immune system?
✔✔ The primary components of the innate immune system include physical barriers (like skin),
phagocytic cells, and antimicrobial proteins.
How do the complement proteins assist in the immune response?
✔✔ Complement proteins enhance the ability of antibodies and phagocytic cells to clear
pathogens and damaged cells.

, What is the role of helper T cells in the immune response?
✔✔ Helper T cells coordinate the immune response by activating other immune cells, including
B cells and cytotoxic T cells.
What is the significance of memory cells in the immune system?
✔✔ Memory cells remember previously encountered pathogens and enable a faster and stronger
response upon subsequent exposures.
How does the body develop immunological tolerance?
✔✔ Immunological tolerance is developed when the immune system learns to recognize and not
attack the body’s own tissues.
What are the main differences between a primary and secondary immune response?
✔✔ The primary immune response occurs upon first exposure to a pathogen and is slower, while
the secondary immune response is faster and more robust due to memory cells.
How do interferons function in the immune system?
✔✔ Interferons are signaling proteins released by infected cells that help other cells resist viral
infection.
