1. Lymph nodes act as filters for the lymphatic system, removing bacteria, viruses, and other harmful substances from the lymph fluid before it is returned to the bloodstream.
2. Lymph plays a crucial role in the immune system by transporting white blood cells, such as lymphocytes, to areas of infection or inflammation to help fight off pathogens and foreign invaders.

Functions of Lymph Nodes:
- Filter and trap pathogens: They contain white blood cells that identify and destroy harmful microorganisms, preventing them from spreading throughout the body. - Produce antibodies: They produce B cells that generate antibodies against specific pathogens, providing immunity.
Functions of Lymph:
- Collects waste and fluid from tissues: It flows through lymphatic vessels and collects waste products, excess fluid, and pathogens from body tissues. - Returns fluid and immune cells to the bloodstream: The lymph transports these collected substances to lymph nodes and eventually returns them to the bloodstream, maintaining fluid balance and supporting the immune system.
