Which system does lymph primarily belong to?

Lymph primarily belongs to the immune system, as it plays a critical role in the body’s defense against pathogens and foreign substances. Lymph, a clear fluid that originates from the interstitial fluid surrounding cells, is collected by lymphatic vessels and transported throughout the body. It contains white blood cells, particularly lymphocytes, which are crucial components of the immune response. As lymph circulates, it passes through lymph nodes, where it is filtered and where immune responses can be initiated against threats such as infections or abnormal cells.

This connection to the immune system is fundamental, as the lymphatic system not only aids in the distribution of immune cells but also helps to remove waste and toxins from tissues, contributing to overall health. While lymph is also involved with vascular component interactions, its primary function is closely tied to the activities of the immune system in protecting the body from diseases.
