Quizplus · Accepted Answer

Red bone marrow produces all types of blood cells, including the immune cells, so it is an organ of the immune system. The spleen filters blood and helps fight infections, making it a part of the immune system. The thymus plays an important role in the maturation and activation of T cells, which are a type of immune cell. Tonsils are part of the lymphatic system and help trap and remove bacteria and other foreign substances, making them a part of the immune system. The thyroid, on the other hand, is not directly involved in immune function.
