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、脾肿大，或血管病变（如下腔静脉扩张）。

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血流会受阻。

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，我想我可以把血止住了。我想它是从下腔静脉出来。

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

最终，所有血液都回流至上腔静脉和下腔静脉，最终抵达右心房。

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。

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。

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.

肝脏处理了所有这些物质，肝脏将血液通过下腔静脉进入体静脉系统送往心脏。

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，流入下腔静脉血液必须向上流动，对抗重力。

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。

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。

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

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间静脉，然后汇聚成弓状静脉、叶间静脉，最终汇入左右肾静脉；肾静脉又与下腔静脉相通。

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右心房。

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.

下腔静脉有更大引流面积，其作用是将脱氧血从横膈膜下所有身体区域回流到心脏。

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.

当下腔静脉同时通过腹腔和胸腔时，腹腔压力增加和胸腔压力降低会将血液向上挤压—流向心脏。

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.

当心房收缩时，右房内血液经三尖瓣进入右室。

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.

确定是否存在门静脉高压症金标准是测量肝静脉压力梯度，即将导管先后插入下腔静脉、门静脉内测量两个压力之间差异。

The inferior vena cava is much longer than the superior vena cava, and you could argue that it has a bigger job, because it returns blood to the heart from all body regions below the diaphragm.

下腔静脉比上腔静脉长得多，可以说它有更大作用，因为它从横膈膜下所有身体区域将血液回流到心脏。
