What are the vessels leading out of the lymph nodes called?

Lymphatic ducts are the vessels that carry lymph away from the lymph nodes. After lymph fluid is filtered through the lymph nodes, it is transported via these ducts, which ultimately channel the lymph back into the bloodstream at the subclavian veins. The primary functions of the lymphatic system include the transportation of lymph, which contains immune cells, and the maintenance of fluid balance within the body. The presence of lymphatic ducts is crucial for this process, as they ensure that the fluid collected from tissues is efficiently returned to circulation after filtration.

The other options do not correctly describe the vessels that transport lymph from the lymph nodes. Lymphatic veins and arteries serve different functions, primarily associated with blood circulation rather than lymph transport. Capillaries, while involved in the initial collection of interstitial fluid, are not the vessels that drain lymph from lymph nodes. Thus, the role of lymphatic ducts in facilitating the flow of lymph is essential for the proper functioning of the immune system and fluid homeostasis in the body.
