Explanation about the Function of Lymph Nodes

Lymph nodes play a crucial role in the immune system as they act as filters for harmful substances in the body. They are responsible for filtering out microorganisms, such as bacteria and viruses, that have been engulfed by lymphocytes. This helps to prevent the spread of infections and diseases throughout the body.

When you are sick, your lymph nodes may swell or become tender. This is a sign that your immune system is actively fighting off an infection. The swelling occurs as a result of increased production of white blood cells and other immune cells within the lymph nodes.

Overall, the lymph nodes are essential for maintaining a healthy immune response and protecting the body from harmful pathogens.
