Question

Quizplus · Accepted Answer

T cells are lymphocytes that are produced and mature in the thymus gland and are responsible for cell-mediated immunity. They act on antigens by recognizing them on the surface of infected or abnormal cells and either directly kill them or stimulate other immune cells to attack them. B cells, on the other hand, are lymphocytes produced in the bone marrow that are responsible for antibody-mediated immunity. Macrophages are a type of white blood cell that engulfs and digests cellular debris, foreign substances, microbes, and cancer cells.
