6.4 B Cells & Humoral Immunity Flashcards
- What is the role of B cells in humoral immunity? - What are the roles of plasma cells and antibodies in the primary immune response? - What is the role of memory cells in the secondary immune response? - How does antigenic variation affect the body's response to infection?
What is another word for body fluids?
Humour
What does humoral immunity involve?
Antibodies
How does a B cell divide?
Mitosis
What two types of cell do B cell clones produce?
Plasma cells
Memory cells
What do plasma cells do?
Secrete antibodies directly
What do the antibodies secreted by plasma cells do?
Destroy the pathogens and any toxins it produces.
What cells are response for the immediate response?
Plasma cells
What is the immediate response known as?
The Primary Immune Response
What do memory cells do?
Circulate in the blood, waiting to encounter the same antigen.
What happens when memory cells encounter their antigen?
They divide rapidly and develop into plasma cells and memory cells.
What is the response of the memory cells known as?
The Secondary Immune Response
