Question

Quizplus · Accepted Answer

The thymus is a gland in the lymphatic system that secretes hormones called thymosins, which aid in the maturation of T-cells, a type of white blood cell. The spleen helps filter blood and stores red blood cells, while lymph nodes filter lymph fluid and trap pathogens. The palatine tonsils aid in filtering pathogens entering through the mouth and nose. However, none of these structures secrete hormone.
