Haematopoietic System: the system that makes blood and blood cells
Dendritic Cells: antigen-presenting cells
Lymphoid Tissues:
• Primary lymphoid tissues- (T-cells = thymus, B-cells = Bone marrow)
• Secondary lymphoid tissues- (lymph nodes, spleen, MALT)
Non-Lymphoid Cells:
• Dendritic cells- antigen presenting cell
• Interdigitating dendritic cell- present antigens to T-cells in paracortex of lymph
nodes
• Follicular dendritic cells- present antigen to B-cells in germinal centres (in 2°
lymph)
• PALS of spleen
• Peyer’s Patch of MALT
lymphocytes are circulated around the body via blood and re-enter lymphatic system
via High Endothelial Venules
