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

不过，来自的血液不含氧。

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

注意，这条大确实会分成和。

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

是吗 我看不到啊。

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

在上。导线的作用就像心脏上的永久性划片。

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

心脏左侧的最高点应为，下面是。

From there the blood goes into the right ventricle and gets pumped into pulmonary artery and eventually into the lungs.

接着，血液从右心房进入右心室并被泵入，最终进入。

Remember how fluid buildup increased pressure in the pulmonary artery?

还记得体液积聚如何增加压力吧？

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

一旦心脏完全发育，来自于左心室，来自于右心室。

And then Bob Temple did it once for a pulmonary hypertension drug.

然后鲍勃·坦普尔曾为一种高压药物这样做过一次。

The whole pulmonary artery burst again, and there was a major, major bleeding.

整个再次破裂，出现了严重的出血。

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

血栓堵在了，导致了心脏变形。

Right atrial enlargement is usually due to pulmonary hypertension.

右心房增大通常由高压引起。

Moreover, it's dilating the pulmonary arteries.

此外，它还在扩张。

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

携带来自于右心室的低氧血液，而静将来自于的富氧血液运至左心房。

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

大指的就是这两条把血液带离心脏的要：和。

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

将脱氧血从心脏输送到。

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，以及从右心室流入。

The greater the pulmonary obstruction, the more deoxygenated blood enters the systemic circulation, the more severe the symptoms.

梗阻越严重，越多低氧的血进入全身循环，症状越严重。

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，患者右心室和的氧饱和度就升高了。

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，右室血液经瓣进入，同时三尖瓣关闭防止血液回流至心房。
