Which system aids immunity and fluid balance?

The lymphatic system is responsible for both immunity and fluid balance. It returns excess interstitial fluid to the bloodstream, which helps prevent edema, and it transports immune cells and antigens to lymph nodes where immune responses can be activated. Lymph nodes, the spleen, thymus, and tonsils all play roles in recognizing invaders and shaping the body’s defenses. Chyle is a type of lymph that carries absorbed fats from the gut, so it’s part of the lymphatic system, not a separate system. Pathogens are disease-causing organisms, not a system. Fluid distribution is a general concept, not a specific system that handles immune surveillance and fluid return. So the lymphatic system best fits.
