Plasma cells are cells responsible for production of circulating immunoglobulins.
Explanation:
Plasma cells are white blood cells that are produced from the bone marrow and they secrete and produce antibodies like immunoglobulin.
Immunoglobulins are antibododies produced by plasma cells that act as immune response by recognizing and binding to particular antigens such as bacteria, viruses in order to destroy them.
B lymphocytes are thymus-independent cells that express intrinsically produced immunoglobulins on their external membranes and upon stimulation by antigen differentiate into plasma cells that produce and secrete large numbers of antibody molecules
