No, they consume energy (calories) for their activities. Through metabolic activity they might produce some heat but in terms of keeping the body warm, this is achieved by the muscles.
They don't produce anything. Lymph nodes take excess fluid out of your body, which are extracted from your lymph nodes and travel through your lymph vessels. Then, the body gets rid of this fluid. (you can just guess that part)
tiny vessels
Lymph nodes can produce and contain lymph fluid, but they do not typically leak fluid. If a lymph node is damaged or infected, it may become enlarged or tender, but leakage of lymphatic fluid from a lymph node is not a common occurrence.
