Which of the following is NOT a function of the lymphatic system?

• A. Returning excess interstitial fluid to circulation
• B. Transporting red blood cells
• C. Housing immune cells for body defense
• D. Filtering lymph fluid

Answer: (B)

The lymphatic system has several key functions, and one of its primary roles is to manage fluids and immune responses within the body. Returning excess interstitial fluid to circulation is crucial in maintaining fluid balance and preventing edema. The lymphatic system also filters lymph fluid through lymph nodes, which is vital for identifying and responding to pathogens and other foreign substances. Furthermore, housing immune cells like lymphocytes is fundamental to the body’s defense mechanisms against infections. Transporting red blood cells, however, is not a function of the lymphatic system. This task is primarily handled by the circulatory system, specifically the blood vessels, which carry red blood cells throughout the body to deliver oxygen and remove carbon dioxide. The lymphatic system operates separately, focusing on lymph fluid, interstitial fluid, and immune cell functions rather than the transportation of red blood cells.
