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

是遍布人体的道。

The middle layer is the lamina propria and it contains blood and lymph vessels.

粘膜层的中层为固有层，内含。

These lymphatic vessels mainly drain into a group of lymph nodes in the axilla, or the armpit.

这些主要通向腋窝结。

Fatty acids and glycerol can easily pass through the small intestinal epithelium and into the lymphatics.

脂肪酸甘油三酯都能轻易穿过肠壁进入。

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。

Lymph and blood vessels carry those cells all over the body, and they can go on to form tumors.

把这些细胞运输到身体各个部位，然后这细胞会继续形成新肿瘤。

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阻塞的疾病或因素。

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

癌细胞也可以进入并阻塞细小的，使集到组织间隙。

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

为防止返流，静脉一样有瓣膜。

People might wear compressive bandages that can help keep fluid from accumulating, and compression lymphatic massages can help with lymph flow.

患者可以穿着弹力绷带以防止液体积，同时加压按摩可帮助流动。

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。

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

一旦进入毛细，它就会通过更大、壁更厚的，然后是干，再然后是导。

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

毛细是极度通透的，因为它们的壁仅由松散重叠的内皮细胞构成，形成单向的微小瓣膜。

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

毛细是最小的，它们广泛分布于间质。

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。

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。

Because the lymphatics are under low pressure, they need a little help to propel lymph.

由于处于低压状态，因此需要一点帮助来推动。

It is through the capillaries in the villi that completely digested nutrients pass into the bloodstream and lymph vessels.

通过绒毛中的毛细被完全消化的营养物质进入液。

By theway, the thinner walls of lymphaticvessels are easier to penetrate, which is why examininglymph nodes plays a major role in cancer detection.

因为壁很薄，极易穿透，所以通过的检查可以诊断癌症。

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。
