Also, a filter can be surgically placed in the inferior vena cava to prevent pulmonary embolisms.

也可以放置下腔滤器来防止肺栓塞的发生。

CT scan or MRI help diagnose ascites, cirrhosis, splenomegally or vascular alterations like inferior vena cava dilatation.

CT扫描或MRI有助于诊断腹水、肝硬化、脾肿大，或管病变（如下腔扩张）。

Even partial compression of the superior vena cava can cause the venous pressure behind the obstruction to increase.

局部迫上腔甚至能造成阻断后方的升高。

But in some situations, an obstruction may prevent blood flow from the portal vein towards the inferior vena cava.

但有时从门流到下腔的流会受阻。

Got it. Wait, I-I think I can localize the bleeding. I think it's coming from the inferior vena cava.

搞定。等等，我想我可以把止住了。我想它是从下腔出来的。

This happens when there's an obstruction in the passage of blood from the portal vein towards the vena cava.

当液从门流向腔的通道阻塞时，就会发生这种。

I use a little shade called cava and bellini.

我使用一种叫做 cava 和 bellini 的小色号。

The superior vena cava is found in the upper chest.

上腔位于上胸部。

On the right side, the superior vena cava, ascending aorta, right ventricle, left ventricle, and inferior vena cava should all be visible.

在心脏右侧，分别是上腔、升主动、右心室、左心室和下腔。

The superior vena cava resembles a drain that leads down into the heart.

上腔像通向心脏的引流管。

Once the liver processes all these substances, it sends the blood to the heart through the inferior vena cava to enter the systemic venous system.

一旦肝脏处理了所有这些物质，肝脏将液通过下腔进入体系统送往心脏。

So, if you think about it, the blood that drains into the inferior vena cava has to move upward, against gravity.

所以，如果你仔细想想，流入下腔的液必须向上流动，对抗重力。

So far, we've learned that blood returning to the heart from head to toe drains into the superior and inferior vena cava.

到目前为止，我们已经了解到，液从头到脚流回心脏，流入上下腔。

Ultimately, all of the blood ends up in the superior or inferior vena cava and dumps into the right atrium.

最终，所有的液都回流至上腔和下腔，最终抵达右心房。

The job of the superior vena cava is simple, and like many other major veins in the body, it is nothing more than a transportation tube.

上腔的作用很简单，和体内其他许多主要一样，它不过是一个运输管。

This is a good way to think about the superior vena cava, because its job is to drain (or return) deoxygenated blood straight down into the right atrium.

这是考虑上腔的好方法，因为它的工作是将脱氧的液直接排入（或回流）到右心房中。

These peritubular capillaries then reunite to become the cortical radiate veins, then the arcuate veins, then interlobar veins and finally into the left and right renal veins which connect to the inferior vena cava.

这些肾小管周围毛细管网将重新汇聚成小叶间，然后汇聚成弓状、叶间，最终汇入左右肾；肾又与下腔相通。

As the inferior vena cava passes through both abdominal and thoracic cavities, an increase in abdominal pressure together with a decrease in thoracic pressure squeeze the blood upward- toward the heart.

当下腔同时通过腹腔和胸腔时，腹腔力增加和胸腔力降低会将液向上挤—流向心脏。

Blood from the upper body returns via the superior vena cava, blood from the lower body returns via the inferior vena cava.

上半身液通过上腔回流，下半身液通过下腔回流。

The inferior vena cava has a bigger area to drain, and its job is to return deoxygenated blood to the heart from all body regions below the diaphragm.

下腔有更大的引流面积，其作用是将脱氧从横膈膜下的所有身体区域回流到心脏。
