Lymphocytes- are the main warriors of the immune
system and they arise in the red bone marrow.
T cells and B cells protect against antigen.
Activated T cells manage immune response & some
attack & and destroy infected cells.
B cells- protect the body by producing plasma cells
which are daughter cells that secrete antibodies
into the blood.
Lymphoid macrophages also play a huge role in
protection by phagocytizing foreign substance &
help activate T-cells.

This is the most important component of
the immune system 1) because it houses &
provides a proliferation site for lymphocytes
and 2) furnishes an ideal surveillance
vantage point for lymphocytes and
macrophages.
Lymphoid tissues re composed of loose
connection tissue called reticular connective
tissue called reticular connective tissue,
which dominates all the lymphoid organs
except thymus.
