The spleen is responsible for the destruction of old red blood cells and is a major site for the initiation of the immune response. The liver also plays a role in the breakdown of red blood cells but is not as significant of a site for immune response initiation. Bone marrow is the site of red blood cell production and does not play a major role in immune response initiation. Tonsils and thymus are both part of the lymphatic system but are not major sites of red blood cell destruction or immune response initiation.
