1.Lymphatic capillaries are the smallest lymphatic vessels, and they're located throughout the interstitial space.

毛细管是最小的管，它们广泛分布于间质。

2.The vessels are tubes that spread through a person's body.

管是遍布人体的管道。

3.Once the interstitial fluid is in the lymphatic vessels, it's called lymph.

一旦间质液进管中，它就叫做“”。

4.These lymphatic vessels mainly drain into a group of lymph nodes in the axilla, or the armpit.

这些管主要通向腋窝结。

5.The tunica externa also has nerve fibers, lymphatic vessels, and in the biggest vessels, the protein elastin.

外膜也有神经纤维、管，在最大的血管中也有弹性蛋。

6.Lymph and blood vessels carry those cells all over the body, and they can go on to form tumors.

管和血管把这些细胞运输到身体各个部位，然后这细胞会继续形成新肿瘤。

7.Primary lymphedema, on the other hand, is when there isn't some other disease or factor that leads to lymphatic obstruction.

而原发性的水肿有他导致管阻塞的疾病或因素。

8.To keep the lymph from sliding backwards, the lymphatic vessels have valves just like the veins.

为防止返流，管和静脉一样有瓣膜。

9.Once the lymph is inside the lymphatic capillaries, it travels through bigger and thicker-walled vessels, then trunks, and then ducts.

一旦进毛细管，它就会通过更大、管壁更厚的管，然后是干，再然后是导管。

10.Lymphatic capillaries are extremely permeable because their walls are made of endothelial cells that only loosely overlap, forming one-way minivalves.

毛细管是极度通透的，因为它们的管壁仅由松散重叠的内皮细胞构成，形成单向的微小瓣膜。

11.Cancer cells can also enter and block the thin lymphatic vessels, which causes lymph to build up in the interstitial space.

癌细胞也可以进并阻塞细小的管，使聚集到组织间隙。

12.When an infection gets into the tissue, it can slip into a lymphatic capillary and move into a lymphatic vessel.

当感染侵组织，它会进毛细管，从而进管。

13.People might wear compressive bandages that can help keep fluid from accumulating, and compression lymphatic massages can help with lymph flow.

患者可以穿着弹力绷带以防止液体积聚，同时加压管按摩可帮助流动。

14.The middle layer is the lamina propria and it contains blood and lymph vessels.

粘膜层的中层为固有层，内含血管和管。

15.Like veins, we see that lymphatic vessels have thin walls, and the larger ones contain one-way valves.

像静脉一样，我们看到管壁很薄，较大的管含有单向瓣膜。

16.That's where the lymphatic vessels, or lymphatics, come into play: they collect excess interstitial fluid and return it to the blood.

这就是管发挥作用的地方了：它们收集过量的间质液并把它们运回血液。

17.After the lymph is picked up by the lymphatic capillaries, the capillaries converge into larger lymphatic vessels.

毛细血管吸收液后，毛细血管会聚成较大的管。

18.By theway, the thinner walls of lymphaticvessels are easier to penetrate, which is why examininglymph nodes plays a major role in cancer detection.

因为管壁很薄，极易穿透，所以通过的检查可以诊断癌症。

19.It is through the capillaries in the villi that completely digested nutrients pass into the bloodstream and lymph vessels.

通过绒毛中的毛细血管被完全消化的营养物质进血液和管。

20.Lymphatic capillaries are the smallest lymphatic vessels and collect fluid from the surrounding tissues.

毛细管是最小的管，从周围组织收集液体。
