Verified step by step guidance

Understand the function of lymph nodes: Lymph nodes are small, bean-shaped structures that are part of the lymphatic system. They filter lymph fluid, trapping bacteria, viruses, and other foreign particles.

Identify the role of tonsils: Tonsils are lymphoid tissues located at the back of the throat. They help trap pathogens entering through the mouth or nose but are not primarily responsible for filtering lymph fluid.

Examine the function of the thymus: The thymus is an organ located in the chest that is involved in the development of T-cells, a type of white blood cell. It does not filter lymph fluid.

Consider the role of the spleen: The spleen filters blood, removing old or damaged blood cells and pathogens. It is not directly involved in filtering lymph fluid.

Conclude that lymph nodes are the structures responsible for filtering foreign particles from the lymph vessels, as they are specifically designed to trap and destroy pathogens in the lymphatic fluid.
