The brain however, does not have lymphatic vessels that it can use for waste clearance.

但大脑并没有用来清理废物的淋巴血管。

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。

Lymphatic vessels, which serve as pathways for immune cells, have recently been discovered in the brain, and they may also play a role in clearing out the brain's daily waste products.

淋巴管，为免疫细路径的血管，最近被发现存在于大脑中，淋巴管也可能在清除大脑日常代谢物中扮演了重要的角色。

The synovium's composed of loose connective tissue, blood vessels, lymphatic vessels, and on the surface—" Type A" cells that clear cellular debris and " Type B" cells that produce components of synovial fluid, which helps lubricate the two articular surfaces.

滑膜由松散结缔组织、血管、淋巴管组成；在滑膜表面，A型细清理细碎，B型细产生滑液成分，滑液能够润滑两块关节的表面。

The extracellular component includes both the intravascular space - the space within the blood and lymphatic vessels and the interstitial space - the space between cells where you typically find fibrous proteins and long chains of carbohydrates which are called glycosaminoglycans.

细外的部分包括管道内空间，即血管和淋巴管内的空间以及间质空间，即细之间的空间，通常能找到纤维蛋白和聚（即黏多）的长链碳水化合物。

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，并送回循环系统。

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。

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膜。

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

一旦间质液进入淋巴管中，它就做“淋巴”。

Instead, the chylomicrons go into special lymphatic vessels called lacteals, which get their name from the fact that the lymph that flows through them looks like milk.

于是乳糜微粒进入做乳糜管的特殊淋巴管，它们因流经此处的淋巴形似牛奶而得名。

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 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。

But there would be lymph nodes and lymphatic vessels throughout your whole body.

但你的全身都会有淋巴结和淋巴管。

These EO3 cells that look like lymphatic vessels, which are normally not in the brain.

这些EO3细看起来像淋巴管，而淋巴管正常情况下并不存在于大脑中。

1652. Thomas Bartolin shows the lymphatic vessels extend throughout the body, and coins the term lymphatics.

1652. 托马斯·巴尔托林展示了淋巴管遍布全身，并创造了“淋巴系统” 一词。

An early description of lymph nodes, small glands where lymphocytes cluster, was recorded by the Greek physician Hippocrates in the 5th century BCE, and Galen of Pergamum in the 2nd century CE wrote about lymphatic vessels.

早在公元前5世纪， 希腊医生希波克拉底就记录了对淋巴结的早期描述，这些小腺体是淋巴细聚集的地方；到了公元2世纪， 帕加马的盖伦则撰写了关于淋巴管的内容。

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。

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。

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。

From there, it drains into the lymphatic vessels as lymph.

由此，它流入淋巴管，转化为淋巴液。
