肺脏是具有丰富淋巴管的脏器。因此,罹患肺癌时易引起淋巴转移。由于淋巴管有滤过的功能,当癌细胞转移入侵之际,会产生机械性的防御(Mechanical barrier);此外,因淋巴结的反应机制,可抑制癌细胞的增殖,从而也将产生生物学的防御(biolo gical barrier)淋巴结虽然有上述功能,但肺内淋巴管,几乎都是毛细管状,从组织学观点来说,它是一层很薄的内皮细胞构成的
The lungs are organs that are rich in lymphatic vessels. Therefore, it is easy to cause lymphatic metastasis when suffering from lung cancer. Because of the filtering function of lymphatic vessels, when a cancer cell metastasizes and invades, it will produce a mechanical barrier. In addition, due to the mechanism of lymph node response, it can inhibit the proliferation of cancer cells, and thus will also produce biological Although the lymph nodes of the biolo gical barrier have the above-mentioned functions, the lymphatic vessels in the lung are almost all capillary. From the histological point of view, it is composed of a thin layer of endothelial cells.
