Quizplus · Accepted Answer

Antibodies are released by plasma cells, which are a type of B lymphocyte. T lymphocytes are responsible for cell-mediated immunity rather than antibody production. Lymph nodes and medullary cords are structures within the immune system where immune cells are located, but they do not release antibodies themselves.
