Organs of immune system/Lymphoid organs

The video describes various organs of the lymphoid system. Immune system / Immune response: Central to the function of all lymphoid organs.
Lymphocytes: The primary white blood cells (B and T cells) that develop and function within these organs.
Maturation / Differentiation: The process by which immune cells become functional (occurs in primary organs).
Proliferation / Activation: The rapid multiplication and initiation of an immune response (occurs in secondary organs).
Antigen: The foreign substance that triggers an immune response.
Filter / Filtration: A key mechanical function, especially of the lymph nodes and spleen, to remove pathogens and debris.
Pathogens: The disease-causing agents (bacteria, viruses, etc.) that the organs defend against.
Organ-Specific Keywords
Organ Key Descriptive Words
Bone Marrow Hematopoiesis, B-cell maturation, stem cells, all blood cells produced.
Thymus T-cell maturation, T-lymphocytes, selection process (self/non-self recognition), crucial in childhood.
Lymph Nodes Filter lymph, bean-shaped, trap pathogens, clustered (neck, armpit, groin), swollen (lymphadenopathy).
Spleen Filter blood, largest lymphoid organ, red pulp (RBC removal), white pulp (lymphocytes), antibody synthesis.
MALT (Mucosa-associated lymphoid tissue) Mucosal lining, unencapsulated tissue, first line of defense, Peyer's patches, tonsils.
Functional Classification Keywords
Primary (Central) Lymphoid Organs: Sites of lymphocyte development and maturation (bone marrow, thymus).
Secondary (Peripheral) Lymphoid Organs: Sites where mature lymphocytes encounter antigens and mount immune responses (spleen, lymph nodes, MALT).
Tertiary Lymphoid Organs: Temporary structures that form at sites of chronic inflammation.
