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

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

毛细血吸收液后，毛细血会聚成较大的。

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.

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