Which Cells are Important Elements That Comprise Cell-Mediated Immunity

Question

Which cells are important elements that comprise cell-mediated immunity?
A) B cells
B) cytotoxic T cells
C) plasma cells
D) complement proteins

Accepted Answer

Cytotoxic T cells are important elements that comprise cell-mediated immunity. They recognize and destroy infected or cancerous cells by directly killing them. B cells are part of the humoral immune response, which involves the production of antibodies by plasma cells. Complement proteins complement the actions of antibodies and also help to destroy pathogens, but they are not directly involved in cell-mediated immunity.
