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.

这就是管发挥作用地方了：它们收集过量间质并把它们运回血。

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.

管，为免疫细胞提供路径血管，最近被发现存在于大脑中，管也可能在清除大脑日常代谢物中扮演了重要角色。

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、管组成；在滑膜表面，A型细胞清理细胞碎，B型细胞产生滑成分，滑能够润滑两块关节表面。

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.

细胞外部分包括管道内空间，即血管和管内空间以及间质空间，即细胞之间空间，通常能找到纤维蛋白和叫糖胺聚糖（即黏多糖）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途径，那么将填满这个间隙，不过幸好，胸膜里管能将流出胸膜腔，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，它会进入毛细管，从而进入管。

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。

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

一旦间质进入管中，它就叫做“”。

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.

于是乳糜微粒进入叫做乳糜管特殊管，它们因流经此处形似牛奶而得名。

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、管，在最大血管中也有弹性蛋白。

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

毛细管是最小管，它们广泛分布于间质。

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

但你全身都会有结和管。

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

这些EO3细胞看起来像管，而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·尔托林展示了管遍布全身，并创造了“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结早期描述，这些小腺是细胞聚集地方；到了公元2世纪， 帕加马盖伦则撰写了关于管内容。

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.

随着管周围肌肉收缩和放松，血通过血管被挤向心脏，这就像挤压牙膏管底部一样。

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

毛细血管吸收后，毛细血管会聚成较大管。

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——主要管作用。

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

由此，它流入管，转化为。
