Which of the following is NOT classified as a lymphatic organ?

Spleen
Thymus
Liver
Tonsils

The correct answer is: Liver

The liver is not classified as a lymphatic organ, while the other options—spleen, thymus, and tonsils—are integral parts of the lymphatic system. The spleen plays a crucial role in filtering blood, recycling iron, and serving as a reservoir for blood, all while facilitating immune responses by producing lymphocytes. The thymus is essential for the maturation of T cells, which are vital to the adaptive immune system. Tonsils are part of the lymphatic system's first line of defense and help trap pathogens that enter through the mouth and nose, contributing to immune surveillance. In contrast, although the liver has immune functions, such as filtering blood and metabolizing substances, it is primarily involved in digestion and metabolism rather than serving a direct role in the lymphatic system. Therefore, identifying the liver as not being a lymphatic organ reflects a clear understanding of the specific roles and classifications within the body's systems.
