Explanation:
Detailed explanation-1: -Effector B cells can begin secreting antibody while they are still small lymphocytes, but the end stage of their maturation pathway is a large plasma cell (see Figure 24-7B), which continuously secretes antibodies at the astonishing rate of about 2000 molecules per second.
Detailed explanation-2: -B lymphocytes originate in the bone marrow; their goal is to recognize an antigen. Each of them responds to the antigen in a specific way, as it expresses specific antibodies on the membrane (IgM, CD79a, and CD79b).
