Quizplus · Accepted Answer

Adaptive immunity depends upon the activity of B cells, which produce antibodies to recognize and neutralize specific antigens, and T cells, which directly attack infected cells and regulate the immune response. Natural killer cells and neutrophils are innate immune cells that provide immediate defense against pathogens, but do not have the specificity or memory of adaptive immune cells.
