When the body detects an infection or abnormality, lymphocytes within the lymph nodes multiply as well as produce antibodies to combat off the intruders. Macrophages as well as dendritic cells act as scavengers, swallowing up and also digesting foreign fragments to avoid further harm.

• Lymph nodes are an important part of the immune system.
• They assist filter lymph and capture foreign compounds.
• Lymphocytes, macrophages, and dendritic cells collaborate within the nodes to eliminate infections and illness.
