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.
