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

寻找肺动脉高压的治愈方式。

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

来开发肺动脉高压的医治方法。

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。导线的作用就像心脏上的永久性划片。

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

心室流主动脉，右心室流肺动脉。

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。

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

这个声音可在主动脉瓣和肺动脉瓣听诊区被清晰地听到。

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。

Remember how fluid buildup increased pressure in the pulmonary artery?

还记得体液积聚如何增加肺动脉压力吧？

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

心脏侧的最高点应为主动脉弓，下面是肺动脉。

Right atrial enlargement is usually due to pulmonary hypertension.

右心房增大通常由肺动脉高压引起。

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

栓堵在了肺动脉，导致了心脏变形。

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

大动脉指的就是这两条把液带离心脏的主要动脉：主动脉和肺动脉。

Later in life, though, from years of increased pulmonary blood volume, patients might develop pulmonary hypertension, or higher pressures on the pulmonary side.

而在日后，由于数年的肺动脉流量增加，患者可能患有肺动脉高压，即肺动脉的压力会高些。

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

一旦心脏完全发育，可见主动脉来自于心室，肺动脉来自于右心室。

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，边的主动脉瓣右边的肺动脉瓣安静地打开。

This time, though, that blood comes from the pulmonary arteries, carrying deoxygenated blood.

不过，来自肺动脉的液不含氧。

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

当心室收缩时，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心房。

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

肺动脉将脱氧心脏输送到肺。

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心室的低氧液，而肺静脉将来自于肺的富氧液运至心房。
