Question

Quizplus · Accepted Answer

B cells are specifically responsible for antibody-mediated immunity, also known as humoral immunity. When a B cell recognizes a foreign antigen, it differentiates into plasma cells which produce and secrete antibodies that bind to and neutralize the antigen. T cells, on the other hand, are responsible for cell-mediated immunity. Platelets are involved in blood clotting, RBCs transport oxygen and carbon dioxide, and complement is a group of proteins that work together to help destroy pathogens.
