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

毛细淋巴管是最小的淋巴管，它们广泛分布于间质。

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

淋巴管是遍布人体的管道。

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

一旦间质液进入淋巴管中，它就叫做“淋巴”。

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

这些淋巴管主要通向腋窝淋巴结。

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

外有神经纤维、淋巴管，在最大的血管中有弹性蛋。

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

淋巴管和血管把这些细胞运体各个部位，然后这细胞会继续形成新肿瘤。

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

而原发性的淋巴水肿没有其他导致淋巴管阻塞的疾病或因素。

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

为防止淋巴返流，淋巴管和静脉一样有瓣。

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

一旦淋巴进入毛细淋巴管，它就会通过更大、管壁更厚的淋巴管，然后是淋巴干，再然后是淋巴导管。

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

毛细淋巴管是极度通透的，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。

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

癌细胞可以进入并阻塞细小的淋巴管，使淋巴聚集组织间隙。

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

当感染侵入组织，它会进入毛细淋巴管，从而进入淋巴管。

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，同时加压淋巴管按摩可帮助淋巴流动。

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

粘层的中层为固有层，内含血管和淋巴管。

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

像静脉一样，我们看淋巴管壁很薄，较大的淋巴管含有单向瓣。

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

这就是淋巴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。

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

淋巴毛细血管吸收淋巴液后，毛细血管会聚成较大的淋巴管。

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

因为淋巴管壁很薄，极易穿透，所以通过淋巴的检查可以诊断癌症。

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入血液和淋巴管。

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

毛细淋巴管是最小的淋巴管，从周围组织收集液体。
