How is immunoglobulin made?
Immunoglobulins, more commonly referred to as antibodies.- Immunoglobulins/antibodies are synthesized by plasma cells which is a specialized type of B-cell. Immature B-cells are produced in red bone marrow and then migrating to the spleen where some of them mature to a mature B-cell. A mature B-cell can differentiate into either a memory B-cell or a plasma cell."- In human adults, Immunoglobulins are synthesized by plasma cells (specialized type of B-cell) which in turn originates from red bone marrow in large bones (eg. femur).
What do Mature B cells do?
Mature B cells produce immunoglobulins
Why b cells are named so?
B-cells are matured in bone marrow. This is why they are called B-cells ("B" from bone). Similarly T-cell become mature in Thymus gland ("T" from Thymus).
When an antigen stimulates b or t cells these b or t cells produce identical lymphocytes called what?
plasma cells
An antigen stimulates B cells to produce a specific what?
Antibody

Which type of white blood cell that surrounds and kills invading cells removes dead cells and stimulates the action of other immune cells?
Macrophages, sometimes called phagocytes, engulf pathogens and cell debris and trigger T-cells and B-cells.
Do B cells develop in the thymus?
No. Both B- and T-cell precursors come from the bone marrow. B-cells hang around in bone marrow to mature (hence the "B"). T-cells develop in the thymus (hence the "T").
When an antigen stimulates b or t cells these b or t cells produce identical lymphocytes called what?
plasma cells
Do lymphocytes reside permanently in lymphoid tissue then move to other part of body?
Lymphocytes arise in red bone marrow, they then mature into T cells or B cells, when actived the mature cells attack infected cell
Antigens cause immature B cells to?
When a B cell detects an antigen, it will engulf it and then display it on its cell surface with an MHC molcule. This antigen/MHC combination is then detected by a T cell - which will send signalling molcules to B cells to multiply and mature into plasma cells (which create antibodies against the antigen) and memory B cells (which 'remember' the antigen for next time).They become plasma cells
An antigen stimulates B cells to produce a specific what?
Antibody
Where do lymphocytes mature so they can attack?
T-Cell mature in Thymus B-Cell mature in Bone Marrow
Where are lymphocyte cells make?
They are made in the bone marrow, but B cells mature in the spleen and T cells mature in the thymus.
Which two mature blood cell types descend from myeloblasts?
B lymphocyte (B Cell)
