Question
What is the function of the primary organs of the lymphatic system? A. Where lymphocytes become active B. Form and mature lymphocytes C. Filter the extracellular fluid D. Monitor the extracellular fluid
Solution
The primary organs of the lymphatic system are the bone marrow and the thymus.
A. Where lymphocytes become active: This function is primarily associated with the secondary lymphatic organs such as the lymph nodes, spleen, and tonsils. These organs provide the site where the lymphocytes become active and mount an immune response.
B. Form and mature lymphocytes: This is the function of the primary lymphatic organs. The bone marrow is where all the cells of the immune system, including lymphocytes, are formed. The thymus is where T lymphocytes mature.
C. Filter the extracellular fluid: This is a function of the lymphatic system as a whole. The lymphatic vessels collect and filter the extracellular fluid, removing bacteria, viruses, and other foreign substances.
D. Monitor the extracellular fluid: This is also a function of the lymphatic system as a whole. The lymphatic system constantly monitors the extracellular fluid for signs of infection or disease. If a foreign substance is detected, the immune response is triggered.
