11、巴管之间有丰富的交通支，参与构成淋巴侧支循环。当炎症、寄生虫、异物或肿瘤栓子阻塞淋巴管，外伤或手术切断淋巴管时，淋巴经交通支回流，形成淋巴侧支循环。l侧支循环的功能：u优点：炎症和外伤时，侧支保证了正常组织和病变组织的淋巴回流；u缺点：淋巴侧支通路可成为病变扩散或肿瘤转移的途径。January,2019Copyright Depart.Anatomy,School of Medicine,Lanzhou University.All right reserved by YP HOU and YF SONG 第二节 淋巴导管 January,2019Copyright Depart.Anatom
