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

不过，来自动脉的血液不含氧。

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

注意，动脉确实会分成主动脉和动脉。

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

在动脉上。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主动脉弓，下面是动脉。

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，以及从右心室流入动脉。

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动脉，最终进入。

Remember how fluid buildup increased pressure in the pulmonary artery?

还记得体液积聚如何动脉压力吧？

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，可见主动脉来自于左心室，动脉来自于右心室。

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

动脉指的就是两把血液带离心脏的主要动脉：主动脉和动脉。

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，患者右心室和动脉的氧饱和度就升高了。

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

整个动脉再次破裂，出现了严重的出血。

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

如果主动脉和动脉两动脉不分开的话，你就会有从心室发出的动脉。

Moreover, it's dilating the pulmonary arteries.

此外，它还在扩张动脉。

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

动脉携带来自于右心室的低氧血液，而静脉将来自于的富氧血液运至左心房。

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

动脉将脱氧血从心脏输送到。

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.

经常发生在腿部的深静脉或从心脏通往部、携带缺氧血的动脉中。

Lastly, G is for great vessels which includes the superior vena cava, inferior vena cava, ascending aorta, aortic arch, pulmonary artery, and descending aorta.

最后，G指血管" Great vessels" ，包括了上腔静脉、下腔静脉、升主动脉、主动脉弓、动脉与降主动脉。

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-动脉转位，即L-TGA，左旋的意思是主动脉主要位于动脉的左侧。

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.

血液从动脉进入较细小的小动脉，最后进入毛细血管。

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.

一旦血液通过动脉瓣，便会进入动脉；动脉将血液从心脏输送到左和右。
