Lymph Node Diagram And Function With Pencil
Lymph nodes are small, bean-shaped structures found throughout the body's lymphatic system. They play a crucial role in filtering lymph fluid, trapping and destroying harmful substances like bacteria and viruses.
Parts:
1. Cortex: The outer region containing lymphoid follicles and germinal centers where immune responses are initiated.
2. Medulla: The inner region containing lymphocytes, plasma cells, and macrophages, which further filter and process lymph.
3. Capsule: The fibrous covering surrounding the node, providing structural support.
Functions:
1. Filter lymph: Lymph nodes act as filters, trapping foreign particles and pathogens present in lymph fluid.
2. Immune response initiation: They house immune cells such as lymphocytes and macrophages, which initiate immune responses against pathogens.
3. Production of lymphocytes: Lymph nodes are sites where lymphocytes, such as B cells and T cells, mature and proliferate.
4. Storage of immune cells: They serve as reservoirs for immune cells, ensuring a rapid response to infections.
