Study Notes
Major Immune Tissues: Lymphoid Organs
- Immune system comprised of central and peripheral lymphoid tissues.
- Central lymphoid tissues are involved in the origin and maturation of immune cells.
- Peripheral lymphoid tissues play a crucial role in maintaining immune cells and initiating immune responses.
Primary Lymphoid Organs
- Bone marrow and thymus serve as primary sites for the development and maturation of immune cells.
Bone Marrow
- Source of all hematopoietic (blood-forming) progenitor (stem) cells.
- Responsible for the production of T lymphocytes and B lymphocytes.
- Key site for the maturation process of B lymphocytes.
Thymus
- Integral structure for the maturation of T lymphocytes.
- Plays a critical role in developing a functional immune response.
