    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.
