Which system helps remove excess fluids from the body?

• A. Immune system
• B. Nervous system
• C. Musculoskeletal system
• D. Reproductive system

Answer: (A)

Fluid balance in the body is maintained in part by the lymphatic system, which is a key component of the immune system. It collects excess interstitial fluid that leaks out of capillaries, transports it as lymph, and returns it to the bloodstream, helping keep tissue fluid levels and blood volume stable. This drainage also supports immune defenses by filtering lymph through lymph nodes. While the urinary system handles most bodily water excretion (not listed here), the lymphatic/immune system is the best match among the given options for removing excess fluids.
