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成小叶，然后汇聚成弓状、叶，最终汇入左肾；肾又与下腔相通。

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，上半身的血液则流入上腔，由这两者将血液送回。

So, the bigger the gap is between the high pressure in your ventricles and aorta, and the low pressure in your vena cava and atria, the faster a liter of blood will flow through your system.

所以，室和主动的高压和腔和的低压之的差距越大，一升血液流过你系统的速度就越快。

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.

侧的肺上沟瘤还会压迫上腔；上腔汇集头部、上胸部和上肢的血液。

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.

一旦肝处理了所有这些物质，肝将血液通过下腔进入体系统送往。

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

在侧，分别是上腔、升主动、室、左室和下腔。

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。

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。我想它是从下腔出来的。

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

当血液从门流向腔的通道阻塞时，就会发生这种情况。

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

局部压迫上腔甚至能造成阻断后方的压升高。

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和下腔，最终抵达。

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，或血管病变（如下腔扩张）。

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、下腔、升主动、主动弓、肺动与降主动。

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血流会受阻。

The gold standard for determining if there is portal hypertension is obtaining a hepatic venous pressure gradient measurement where a catheter is inserted inside the inferior vena cava and then inside the portal vein to measure the difference between both pressures.

确定是否存在门高压症的金标准是测量肝压力梯度，即将导管先后插入下腔、门内测量两个压力之的差异。

If you sleep flat on your back, as Dr. Goffman said, the structure we're most worried about is the inferior vena cava, so it's this big blood vessel bringing blood back up to your heart and your head.

如果你平躺在背上睡觉， 正如戈夫曼博士所说，我们最担的结构是下腔，这是将血液带回和头部的一条大血管。

Blood returning from tissues other than the lungs enters the heart by way of the venae cavae; the superior vena cava and the inferior vena cava. The venae cavae empty into the right atrium.

当收缩时，内血液经三尖瓣进入室。

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。

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回流，下半身血液通过下腔回流。

The superior vena cava is found in the upper chest.

上腔位于上胸部。
