The role of T cells in the adaptive immune response is to:

• Directly attack infected cells and help coordinate the immune response.

• Produce antibodies to neutralize pathogens.

• Act as physical barriers to prevent pathogen entry.

• Store memory of pathogens for faster future responses.

The role of B cells in the adaptive immune response is to:

• produce antibodies to target specific antigens

• phagocytose pathogens directly

• activate cytotoxic T cells

• release histamine during allergic reactions
