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

毛管是最小的管，它们广泛分布于间质。

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

管是遍布人体的管道。

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

而原发性的水肿没有其他导致管阻塞的疾病或因素。

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

外膜有经纤维、管，在最大的血管中有弹性蛋白。

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

这是显微镜下毛管的作用机。

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

另外，较大的管壁的节律性平滑肌收缩有助于推动。

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

显微镜下的毛管是最小的管，从周围组织收集液体。

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。

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

毛管是极度通透的，因为它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。

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

因此，我们看到较大的管包含单向瓣。

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

毛管是最小的管，从周围组织收集液体。

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

一旦进入毛管，它就会通过更大、管壁更厚的管，然后是干，再然后是导管。

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

癌胞可以进入并阻塞小的管，使聚集到组织间隙。

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。

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

毛血管吸收液后，毛血管会聚成较大的管。

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

右管是一个短小的血管，从右臂和头部和胸部的右侧排出。

Just below the skin over the breast, there's a network of tiny lymphatic vessels that drain the lymph, which is a fluid containing cellular waste products and white blood cells.

在乳房皮肤下，分布着可以引流液的管网络；液中有胞代谢产物和白胞。

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管妻子，她在室内用一条大披巾把自己变成了木乃伊；他一定是从一个选错了的家用器具开始的。

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管；管是遍布全身的闭锁管道；2015年，科学家发现大脑中存在管。

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。
