As the paper explains, nitrate and nitrite have been shown to be good for blood pressure, mitochondrial efficiency, exercise performance, and have a therapeutic effect on pulmonary hypertension.

论文解释道，硝酸盐和亚硝酸盐对血压、线粒体效率、运动能有一的改善作用，对肺动脉高压有一的治疗作用。

So that blood goes from the pulmonary artery into a pulmonary arteriole, which is a little bit smaller and, finally, into a capillary which is the smallest.

血液从肺动脉进入较细小的肺小动脉，最后进入毛细血管。

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。

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

是肺动脉吗 我看不到啊。

They made a decision not to develop any medicines for rare and orphan diseases, and maybe you could use your expertise in satellite communications to develop this cure for pulmonary hypertension.

他们决停止开发治疗罕见病的药品，或许你可以用你在 卫星讯上的专长来开发肺动脉高压的医治方法。

The right ventricle pumps blood through the pulmonary semilunar valve into the pulmonary trunk, which is just a big vessel that splits to form the left and right pulmonary arteries.

右心室过肺半月瓣将血液泵入肺动脉干，肺动脉干只是一个大血管，它分裂形成左右肺动脉。

This usually occurs in the deep veins of the legs or in the pulmonary arteries that carry deoxygenated blood from the heart to the lungs.

这经常发生在腿部的深静脉或从心肺部、携带缺氧血的肺动脉中。

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

在肺动脉上。导线的作用就像心上的永久性划片。

This trip from the right ventricle of the heart, through the pulmonary artery to the lungs, and back to the left atrium of the heart is called the pulmonary circulation.

血液从心右心室，经过肺动脉到肺，再由肺静脉回到心左心房的行程，被称为肺循环。

Yes, she was finding herself unable to walk up the stairs in our house to her bedroom, and after several months of doctors, she was diagnosed to have a rare, almost invariably fatal disease called pulmonary arterial hypertension.

对。她发现自己无法上楼回到自己的卧室。看了几个月的医生以后，她被确诊患了一种罕见的 基本上是致命的疾病叫做肺动脉高压。

A backup of blood in the pulmonary veins and capillary beds can increase the pressure in the pulmonary artery and can also result in fluid moving from the blood vessels to the interstitial space causing pulmonary edema, or congestion.

而血液在肺静脉和毛细血管的积留，会提升肺动脉的压，还会导致体液从血管流入组织间隙，引起肺水肿。

From there — and this is the only time in your body where deoxygenated blood goes through an artery — the blood goes straight through the pulmonary artery into the lungs, where it can pick up oxygen.

这是体内唯一一次缺氧血液过肺动脉，血液直接穿过肺动脉进入肺部，在肺部吸收氧气。

Once it's passed the pulmonary valve, the blood goes into the pulmonary arteries, which carry blood away from the heart to the left and right lung.

一旦血液过肺动脉瓣，便会进入肺动脉；肺动脉将血液从心输送到左肺和右肺。

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吧？

Right after the S1 sound, the aortic and pulmonic valve open up allowing blood to get pushed out to the body and this period of time is called systole.

在S1之后，主动脉瓣和肺动脉瓣打开，分别使得血液流入身体各组织以及肺部，这段时期叫做心收缩期。

On the left side, blood's now pumped from the left ventricle out to the pulmonary artery to the lungs, and then comes back to the left atrium and left ventricle and restarts.

对于左边来说，血液现在从左心室泵到了肺动脉进入肺，最后回到左心房，再进入左心室，然后重复这一循环。

Then, if you place a stethoscope in the left second intercostal space, at the left upper sternal border, you can hear the pulmonary valve closing.

然后，你将听诊器放到左第二肋间隙，在左胸骨上缘，你将听到肺动脉瓣关闭的声音。

Less commonly, babies can have levo-transposition of the great arteries, or l-TGA, with levo meaning that the aorta's primarily to the " left" of the pulmonary artery.

更少见地，宝宝可能会有左旋-大动脉转位，即L-TGA，左旋的意思是主动脉主要位于肺动脉的左侧。

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

既然来了更多含氧高的血液，患者右心室和肺动脉的氧饱和度就升高了。

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

血从左心室流入主动脉，以及从右心室流入肺动脉。
