What causes antibodies to be released into the bloodstream? What
causes antibodies to be released into the bloodstream?

A.When an antigen binds to the receptor of a B cell, it triggers
the B cell to divide to produce plasma cells and memory B cells.
The plasma cells release antibodies, which resemble the B cell
receptor without the transmembrane portion and the portion that
extends into the cytoplasm. This allows the antibodies to be
released into the blood stream.

B.When an antigen binds to the receptor of a B cell, it causes
the B cell to divide to produce plasma cells and memory B cells.
The memory B cells produce and release antibodies through
exocytosis.

C.When an antigen binds to the receptor of a T cell, it causes
the T cell to divide to produce plasma cells and memory cells. The
memory cells produce and release antibodies through exocytosis.

D.When an antigen binds to the receptor of a T cell, it triggers
the T cell to divide to produce plasma cells and memory cells. The
plasma cells release antibodies, which resemble the T cell receptor
without the portion that extends into the cytoplasm. This allows
the antibodies to be released into the blood stream
