T cells and B cells are

Question

Quizplus · Accepted Answer

T cells and B cells are both types of lymphocytes, a type of white blood cell that mediates immune responses.

Note: The other answer choices are not correct. Antigens are molecules that can be recognized by the immune system and can trigger an immune response, but T cells and B cells themselves are not antigens. Antibodies are proteins secreted by B cells that can recognize and bind to specific antigens, but not all lymphocytes are B cells. Phagocytes are a different type of immune cell that can engulf and destroy foreign particles such as bacteria and debris. Macrophages are a type of phagocyte.
