Which of the following is a function of the lymphatic system?

• A. Absorption
• B. Distribution
• C. Produces antibodies, white blood cells (lymphocytes), filters impurities, protects from bacteria
• D. Metabolism

Answer: (C)

Understanding what the lymphatic system does is key here. The lymphatic system is part of the body’s immune defenses, producing white blood cells called lymphocytes and helping generate antibodies through B cells. It also filters impurities and helps protect the body from bacteria by routing pathogens to lymph nodes and other immune organs. The other options point to functions of different systems: absorption is primarily a digestive process, distribution refers to how the circulatory system moves blood, and metabolism involves the chemical processes inside cells. So the description that includes producing antibodies and lymphocytes, filtering impurities, and protecting against bacteria best captures the lymphatic system’s role.
