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

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

为防止返流，和静脉一样有瓣膜。

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、，在最大的中也有弹性蛋白。

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，从而进入。

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

这就是作用的地方了：它们收集过量的间质液并把它们运回液。

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

由此，它流入，转化为液。

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

毛细吸收液后，毛细会聚成较大的。

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

像静脉一样，我们看到壁很薄，较大的含有单向瓣膜。

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.

显微镜下的毛细是最小的，从周围组织收集液体。

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的特殊，它们因流经此处的形似牛奶而得名。

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

因此，我们看到较大的包含单向瓣。

The lymphatic vessels direct lymph toward the upper chest, where they finally return to the venous blood system through one of two large ducts.

将引向上胸部，最后它们通过两条大导之一，返回静脉液系统。
