Question | Answer |
Role of Lymphoid Organs | Origin or initiation of lymph cells |
Central | Thymus & Bone Marrow |
Bone Marrow | B cell production & maturation |
Thymus | Maturation of T-Cells |
Peripheral | Lymph Nodes, spleen, peyers patches |
Peyers Patches | T/B cell activity & antigen trapping collections of cells |
Lymph Node | Encapsulations of B cells connected by lymph vessels |
MALT | Mucosa Associated Lymphatic Tissue i.e Peyers Patches, tonsils |
Role of Lymphocytic Traffic | Immune surveillance that allows activation of lymphocytes at site of infection |
Immune Surveillance | Constant recirculation of lymphocytes to maximise antigen/pathogen detection |
Lymphocyte recirculation | Pass from blood --> Lymph System (if antigen is not present it moves back into the blood) |
Encountering Specific Antigen | Lymphocyte proliferates clonally |
Naive lymphocyte | L. that has not yet encountered antigen it's specific for (recirculate constantly) |
Effector Cell | Activated (armed) lymphocyte by its antigen |
Memory Cell location | Spread throughout host to help recognise recurring antigens |
