The spleen is an important lymphoid organ that acts as a filter for blood-borne antigens. It contains specialized cells called dendritic cells and macrophages that can capture and present antigens to immune cells such as T and B lymphocytes. Therefore, the spleen is considered the primary site of antigen trapping and presentation in the body. The thymus is involved in T cell maturation, but not antigen presentation. Bone marrow is the site of hematopoiesis (blood cell formation) and not specifically involved in antigen presentation. The brain is not involved in immunological processes.
