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

也可以放置下腔静脉滤器来防止肺栓塞的发生。

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，分别是上腔静脉、升主动脉、右心室、左心室和下腔静脉。

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

局部压迫上腔静脉甚至能造后方的静脉压升高。

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

但有时从门静脉流到下腔静脉的血流会受。

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，我想我可以把血止住了。我想它是从下腔静脉出来的。

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、硬化、脾肿大，或血管病变（如下腔静脉扩张）。

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

当血液从门静脉流向腔静脉的通道塞时，就会发生这种情况。

Lastly, G is for great vessels which includes the superior vena cava, inferior vena cava, ascending aorta, aortic arch, pulmonary artery, and descending aorta.

最后，G指大血管" Great vessels" ，包括了上腔静脉、下腔静脉、升主动脉、主动脉弓、肺动脉与降主动脉。

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

最终，所有的血液都回流至上腔静脉和下腔静脉，最终抵达右心房。

The superior vena cava is found in the upper chest.

上腔静脉位于上胸部。

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.

一旦脏处理了所有这些物质，脏将血液通过下腔静脉进入体静脉系统送往心脏。

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

上半身血液通过上腔静脉回流，下半身血液通过下腔静脉回流。

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

上腔静脉像通向心脏的引流管。

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，流入下腔静脉的血液必须向上流动，对抗重力。

Now, the lower half of the body drains into the inferior vena cava and the upper half drains into the superior vena cava both of which dump blood back into the right atrium.

然后，下半身的血液流入下腔静脉，上半身的血液则流入上腔静脉，由这两者将血液送回右心房。

A Pancoast tumor in the right lung apex can also compress a large vein called the superior vena cava which drains blood from the head, upper chest, and arms.

右侧的肺上沟瘤还会压迫上腔静脉；上腔静脉汇集头部、上胸部和上肢的血液。

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，血液从头到脚流回心脏，流入上下腔静脉。

The venae cavae has two divisions: the superior vena cava and the inferior vena cava, and these divisions both return blood to the right atrium of the heart.

上腔静脉和下腔静脉，这些分支都将血液回流到心脏的右心房。

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.

上腔静脉的作用很简单，和体内其他许多主要静脉一样，它不过是一个运输管。

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血管网将重新汇聚小叶间静脉，然后汇聚弓状静脉、叶间静脉，最终汇入左右肾静脉；肾静脉又与下腔静脉相通。
