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 play a crucial role in the body's immune response.

Recognize the process of lymph filtration: As lymph fluid flows through the lymph nodes, it is filtered to remove foreign particles, such as bacteria and viruses, as well as cancer cells.

Identify the role of immune cells: Lymph nodes contain immune cells, such as lymphocytes and macrophages, which help identify and destroy pathogens present in the lymph.

Acknowledge the initiation of immune responses: When pathogens are detected, lymph nodes can initiate an immune response by activating lymphocytes to produce antibodies or by signaling other parts of the immune system.

Clarify misconceptions: Lymph is not converted into blood plasma, absorbed into surrounding tissues, or stored for future use within the lymph nodes. Its primary function is filtration and immune response initiation.
