The lymphatic system plays a critical role in the body's immune response and is often involved in systemic diseases. This system is responsible for maintaining fluid balance, filtering out pathogens, and supporting the immune system by transporting lymph, which contains white blood cells. In conditions such as infections, autoimmune diseases, and cancers, the lymphatic system can be directly affected, leading to symptoms that can influence the whole body. Its interconnectivity with other organs and systems allows it to play a pivotal role in the body's defense mechanisms against systemic diseases.

While the skeletal, digestive, and muscular systems also have important functions, they are not primarily responsible for systemic immune responses in the way that the lymphatic system is.
