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

毛淋巴管是最小的淋巴管，们广泛分于间质。

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

淋巴管是体的管道。

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、淋巴管，在最大的血管中也有弹性蛋白。

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

毛淋巴管是极度通透的，因为们的管壁仅由松散重叠的内皮胞构成，形成单向的微小瓣膜。

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

一旦淋巴进入毛淋巴管，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。

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。

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：们收集过量的间质液们运回血液。

Well, that's the job of the microscopic lymphatic capillaries.

这是显微镜下毛淋巴管的作用机制。

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

毛淋巴管是最小的淋巴管，从周围组织收集液体。

1651. French scientist Jean Pequet highlights the role of the thoracic duct, the main lymphatic vessel.

1651年，法国科学家让·佩凯强调了胸导管——主要淋巴管的作用。

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

淋巴毛血管吸收淋巴液后，毛血管会聚成较大的淋巴管。

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

像静脉一样，我们看到淋巴管壁很薄，较大的淋巴管含有单向瓣膜。

In addition, rhythmic smooth muscle contractions of the larger lymphatic vessel walls help to push the lymph along.

另外，较大的淋巴管壁的节律性平滑肌收缩有助于推动淋巴。

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

显微镜下的毛淋巴管是最小的淋巴管，从周围组织收集液体。

Therefore, we see that the larger lymphatic vessels contain one-way valves.

因此，我们看到较大的淋巴管包含单向瓣。

The right lymphatic duct is a short vessel that drains lymph from the right arm and the right side of the head and chest.

右淋巴管是一个短小的血管，从右臂和头部和胸部的右侧排出淋巴。

All of that excess fluid gets pulled into the afferent lymphatic capillaries, which are closed-ended vessels found throughout the body, even the brain, which is actually discovery made in 2015.

所有剩余的液体流进传入毛淋巴管；淋巴管是全身的闭锁管道；2015年，科学家发现大脑中也存在淋巴管。

But Wrench had a wretched lymphatic wife who made a mummy of herself indoors in a large shawl; and he must have altogether begun with an ill-chosen domestic apparatus.

但是扳手有一个可怜的淋巴管妻子，她在室内用一条大披巾自己变成了木乃伊；他一定是从一个选错了的家用器具开始的。

As muscles that surround the lymphatic vessels contract and relax, the blood is milked through the vessels toward the heart, kind of like squeezing the bottom of a tube of toothpaste.

随着淋巴管周围的肌肉收缩和放松，血液通过血管被挤向心脏，这就像挤压牙膏管的底部一样。

If there were no way out of the pleural space, then it would fill up with fluid, but fortunately, there are lymphatic vessels in the pleura that drain the fluid away and deliver it back into the circulatory system.

如果没有从胸膜腔出来的途径，那么液体将填满这个间隙，不过幸好，胸膜里的淋巴管能将液体引流出胸膜腔，送回循环系统。
