What is the primary function of lymph nodes?

• A. Producing hormones
• B. Filtering lymphatic fluid
• C. Storing blood cells
• D. Generating nerve signals

Answer: (B)

The primary function of lymph nodes is to filter lymphatic fluid. Lymph nodes are integral components of the lymphatic system, which plays a crucial role in the immune response. They act as reservoirs for lymph, a fluid that contains immune cells and waste products. When lymph fluid passes through the lymph nodes, it is filtered to remove harmful substances, such as bacteria, viruses, and other pathogens, along with debris from damaged cells. The filtered fluid then continues to circulate through the lymphatic system, eventually returning to the bloodstream. This filtering process not only helps maintain fluid balance in the body but also supports the immune system in identifying and responding to infections.
