The spleen is an organ of the immune system that filters the blood and removes old or damaged red blood cells, as well as foreign substances such as bacteria and viruses. It also stores white blood cells and is involved in the production of antibodies. The thymus is another immune system organ, but it is responsible for T-cell maturation, not filtering blood. The kidney and liver have important roles in the body but are not directly involved in the immune response or removal of dead/damaged cells from the bloodstream.
