Final answer:
True
The removal of lymphatic structures for disease examination is true; lymph nodes filter out pathogens and house immune cells crucial for responding to diseases.
Step-by-step explanation:
The statement that a removal of lymphatic structures involves the removal of either lymph nodes or lymphoid tissue to be examined for traces of disease is True. Lymph nodes are critical components of the lymphatic system, functioning as filters to remove debris, pathogens, and potentially cancerous cells from the lymph fluid. These structures house immune cells, such as B cells and T cells, which can mount adaptive immune responses when necessary. The extraction and examination of these lymphatic structures can provide vital information about the presence of diseases, including various forms of cancer and infections.
