Question

Quizplus · Accepted Answer

Plasma cells are specialized immune cells that produce antibodies in response to a foreign substance (also known as an antigen) that they encounter. These antibodies then circulate in the bloodstream, binding to and neutralizing the antigen. Lymph nodes and medullary cords are involved in the immune response, but they do not directly produce antibodies. T lymphocytes (also known as T cells) play an important role in the immune response, but they primarily act by recognizing and destroying cells that have been infected with a virus or have become cancerous.
