How do lymphoid organs contribute to immune function in histology?
Lymphoid organs are specialized structures where immune cells are produced, mature, and interact with antigens. They are classified into primary and secondary lymphoid organs:
- Primary lymphoid organs: Include the bone marrow and thymus. Bone marrow is the site of hematopoiesis, where all blood cells, including immune cells, are generated. The thymus is where T cells mature. - Secondary lymphoid organs: Include the lymph nodes, spleen, and mucosa-associated lymphoid tissue (MALT). These organs are sites where immune cells encounter antigens, proliferate, and initiate immune responses.
Histological examination of these organs reveals the organization and interaction of immune cells, providing insights into their functional capacities.
