What is the role of B cells and T cells in specific adaptive immunity?
Understand the Problem
The question is asking about the distinct roles of B cells and T cells in the adaptive immune system, focusing on their specific functions in combating infections. It requires identifying the statement that accurately describes the primary actions of each cell type in adaptive immunity.
Answer
B cells produce antibodies, while T cells eliminate infected cells and support B cells.
B cells create antibodies to target pathogens in the circulatory system. T cells directly eliminate infected or cancerous cells and assist B cells in their response to eliminate pathogens.
Answer for screen readers
B cells create antibodies to target pathogens in the circulatory system. T cells directly eliminate infected or cancerous cells and assist B cells in their response to eliminate pathogens.
More Information
B and T cells are lymphocytes that play a key role in adaptive immunity. B cells are responsible for humoral immunity, while T cells are responsible for cell-mediated immunity.
Tips
A common mistake is thinking B cells directly kill pathogens, while they produce antibodies that neutralize or mark pathogens for destruction.
