Question

Where do long-lived plasma cells actively produce antibodies to specific antigens?

A. Spleen white pulp
B. Circulatory memory B cells
C. Lymph nodes
D. Bone marrow
E. Germinal centers

Answer 1

Plasma B cells actively produce antibodies to specific antigens in the bone marrow.

Step-by-step explanation:

Plasma B cells actively produce antibodies to specific antigens in the bone marrow. After B cells are activated by binding to an antigen, they differentiate into plasma cells. These plasma cells often leave the secondary lymphoid organs and migrate back to the bone marrow, where they continue to produce antibodies.
