Immune system
The immune system uses white blood cells but they are produced and are part of the circulatory system.
Red blood cells and white blood cells belong to the circulatory system. White cells are also found in the lymphatic system and are important in the immune response. Red blood cells are also found in the spleen. The spleen breaks down old red blood cells and recycles them and acts as a reservoir for red blood cells when excess bleeding occurs.
There are billions of white blood cells that are in the circulatory system. A normal white blood count is between 4,500 to 10,000 white blood cells per microliter.

lymph system
White blood cells are part of two systems: the circulatory system and the lymphatic system.
The white blood cells in the lymphatic system are known as lymphocytes. They are essentially just a small leucocyte (a white blood cell).
white and red blood cells sorry.
White blood cells are part of the immune system's defense. White blood cells flock to irritations and infections to heal or eliminate them.
Located (obviously) in the blood, a white blood cell's job is to find and eliminate potential threats to the human body. The system of eliminating threats such as these from the body is undertaken by the IMMUNE system.
