So how on earth did you get access to this drug?

来开发肺动脉医治方法。

But not everyone who has this disease has been so fortunate.

寻找肺动脉治愈方式。

Is it the P.A.? I'm not seeing it.

是肺动脉吗 我看不到啊。

And that's up in the pulmonary artery. The wire lead acts like permanent paddles on a heart.

在肺动脉上。导线作用就像脏上永久性划片。

Blood flows from the left ventricle into the aorta and from the right ventricle into the pulmonary arteries.

从左室流主动脉，以及从右室流肺动脉。

This is heard loudest in the aortic valve and pulmonary valve area.

这个声音可以在主动脉瓣和肺动脉瓣听诊区被清晰地听到。

But, unlike the tricuspid valve, the pulmonary valve doesn't have any of those chordae tendineae.

但与三尖瓣不同，肺动脉瓣没有腱索。

On the left side of the heart, the aortic arch should be the highest up followed by the pulmonary artery.

脏左侧最点应为主动脉弓，下面是肺动脉。

Notice though, that this one big artery does split into the aorta and pulmonary artery.

注意，这条大动脉确实会分成主动脉和肺动脉。

The " great arteries" , are these two main arteries taking blood away from the heart —the aorta and pulmonary artery.

大动脉指就是这两条把液带离脏主要动脉：主动脉和肺动脉。

Remember how fluid buildup increased pressure in the pulmonary artery?

还记得体液积聚如何增加肺动脉力吧？

Once it's fully developed, the aorta comes from the left ventricle and the pulmonary artery comes from the right ventricle.

一旦脏完全发育，可见主动脉来自于左室，肺动脉来自于右室。

A blood clot wedged into the lungs causing his heart to disfigure.

栓堵在了肺动脉，导致了脏变形。

Right atrial enlargement is usually due to pulmonary hypertension.

右房增大通常由肺动脉引起。

And to do that, the aortic valve, on the left side, and the pulmonic valve, on the right side, quietly open up.

为泵出液，左边主动脉瓣以及右边肺动脉瓣安静地打开。

If these two great arteries, the aorta and pulmonary artery, don't divide, you essentially have this massive artery coming from both ventricles.

如果主动脉和肺动脉这两条大动脉不分开话，你就会有这条从室发出大动脉。

Pulmonary vessels include the pulmonary artery and its branches, and the veins that drain the lung capillaries.

肺动脉携带来自于右室低氧液，而肺静脉将来自于肺富氧液运至左房。

Since there's more oxygenated blood over here, patients will have an increased oxygen saturation in the right ventricle and pulmonary artery.

既然来了更多含氧液，患者右室和肺动脉氧饱和度就升了。

When the atria contracts, blood in the right atrium is forced through the tricuspid valve into the right ventricle.

当室收缩时，右室液经肺动脉瓣进肺动脉，同时三尖瓣关闭防止液回流至房。

The pulmonary arteries carry deoxygenated blood from the heart to the lungs.

肺动脉将脱氧从脏输送到肺。
