    The lymphatic system is a part of the circulatory system, comprising a network of conduits called lymphatic vessels that carry a clear fluid called lymph (from Latin lympha "water goddess"[1]) unidirectionally towards the heart. The lymphatic system was first described independently by Olaus Rudbeck and Thomas Bartholin. The lymph system is not a closed system. The circulatory system processes an average of 20 liters of blood per day through capillary filtration which removes plasma while leaving the blood cells. Roughly 17 liters per day of that gets reabsorbed directly into the blood vessels. The primary function of the lymph system is to provide an accessory route for these excess 3 liters per day to get returned to the blood.[2] So lymph is essentially recycled blood plasma.

    You are basically correct. They are both "circulatory" systems, because they both "circulate" something. One is not usually considered to be part of the other - but they are related. The lymph consists of fluid lost from the bloodstream through the leaky walls of capillaries. That lost fluid is gathered up by the many lymphatic vessels, eventually into the thoracic duct and the right lymphatic duct. Those 2 large lymphatic vessels return that lymph to the blood by dumping it into the subclavian veins (under the clavicles). The lymphatic system is also closely related to the immune system, because on the way back to the bloodstream, the lymph is carried through lymph nodes - which are filled with white blood cells. White blood cells are the active cells of the immune system. All 12 organ systems are related to one another in some ways.
