What does the lymphatic system also refer to?

The lymphatic system is primarily associated with the immune system. This network of vessels and organs is crucial for transporting lymph, a fluid that contains infection-fighting white blood cells, throughout the body. The lymphatic system plays a pivotal role in immune responses by filtering pathogens and waste products and facilitating the maturation and proliferation of lymphocytes, which are a type of white blood cell critical for the immune defense.

While there may be overlaps in function with other systems, such as the circulatory system (which also transports fluids), the unique role of the lymphatic system in immune surveillance and response defines its primary association with the immune system. This connection highlights the importance of maintaining a functional lymphatic system to support overall health and protect against infections.
