Which of the following is a waste product removed by the lymphatic system?

The lymphatic system plays a critical role in maintaining the body’s fluid balance and immune function. One of its primary functions is to filter and remove waste products, specifically toxins, from the interstitial fluid. Toxins can originate from various sources, including metabolic processes and environmental exposures, and if not properly managed, they can lead to negative health effects.

The lymphatic system collects this fluid, known as lymph, which contains immune cells, waste materials, and toxins. As lymph circulates through the lymph nodes, it is cleared of these harmful substances before returning to the bloodstream. Therefore, the removal of toxins is a significant aspect of the lymphatic system's role in detoxification and maintaining overall health.

In contrast, oxygen and carbon dioxide are gaseous substances directly involved in respiration and not typically classified as waste products removed by the lymphatic system. While excess nutrients can accumulate, they are not the primary focus of the lymphatic system, which is more concerned with detoxification and immune response. Thus, the correct answer is that the lymphatic system is specifically responsible for removing toxins.
