Function of the lymphatic system?

• A. Transports oxygen
• B. Regulates body temperature
• C. Produces hormones
• D. Carries waste and impurities away from cells

Answer: (D)

The lymphatic system is responsible for draining interstitial fluid and wastes from tissues and returning it to the bloodstream, while also supporting immune function. Lymphatic vessels collect fluid that leaks from capillaries, transport it as lymph to lymph nodes for filtering, and then return cleaner fluid to circulation. This waste- and impurity-draining role fits the statement that the system carries waste and impurities away from cells. Other options describe functions of different systems: transporting oxygen is done by red blood cells in the circulatory system; regulating body temperature is mainly a function of the skin and circulatory responses; producing hormones is the job of the endocrine system.
