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，心室和主动的高压和腔静和心房的低压之间的差距越大，一升过你系统的速度就越快。

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，肝脏将通过下腔静进入体静系统送往心脏。

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静，然后汇聚成弓状静、叶间静，最终汇入左右肾静；肾静又与下腔静相通。

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、升主动、右心室、左心室和下腔静。

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。我想它是从下腔静出来的。

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

也可以放置下腔静滤器来防止肺栓塞的。

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

当从门静向腔静的通道阻塞时，就会这种情况。

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

局部压迫上腔静甚至能造成阻断后方的静压升高。

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（如下腔静扩张）。

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

但有时从门静到下腔静的会受阻。

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.

确定是否存在门静高压症的金标准是测量肝静压力梯度，即将导管先后插入下腔静、门静内测量两个压力之间的差异。

I use a little shade called cava and bellini.

我使用一种叫做 cava 和 bellini 的小色号。

There's cava, the brancava is big in Denver or there's sweet greens where you usually go through the line.

有卡瓦酒，而布朗卡瓦在丹佛很受欢迎，还有甜菜叶沙拉，你通常要排队购买。

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.

上腔静的作用很简单，和体内其他许多主要静一样，它不过是一个运输管。

The superior vena cava is found in the upper chest.

上腔静位于上胸部。

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向上挤压—向心脏。

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

上腔静像通向心脏的引管。

Therefore, if we take into consideration the superior vena cava's appearance and name, we can easily define it as the large vein that returns deoxygenated blood to the heart from the head and arms.

因此，如果我们考虑上腔静的外观和名称，我们很容易将其定义为从头部和手臂将脱氧返回心脏的大静。

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.

这是考虑上腔静的好方法，因为它的工作是将脱氧的直接排入（或回）到右心房中。

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，入下腔静的必须向上动，对抗重力。
