Describe 8 functions of lymph nodes??

1. Filtration: Lymph nodes act as filters for lymph fluid, removing debris, pathogens, and other harmful substances before the fluid is returned to the bloodstream.

2. Immune response: Lymph nodes contain immune cells, such as lymphocytes and macrophages, which help to identify and destroy pathogens, such as bacteria and viruses.

3. Production of antibodies: Lymph nodes play a key role in the production of antibodies, which are proteins that help the immune system to recognize and neutralize foreign invaders.

4. Storage of immune cells: Lymph nodes store immune cells, such as memory B cells and T cells, which can quickly respond to future infections by recognizing and attacking specific pathogens.

5. Activation of immune cells: Lymph nodes help to activate immune cells, such as dendritic cells, which present antigens to T cells, triggering an immune response.

6. Regulation of inflammation: Lymph nodes help to regulate inflammation by releasing cytokines, which are signaling molecules that control the immune response.

7. Surveillance: Lymph nodes act as surveillance centers, monitoring the body for signs of infection or disease and coordinating the immune response to protect against threats.

8. Drainage: Lymph nodes help to drain excess fluid from tissues, preventing swelling and maintaining proper fluid balance in the body.
