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

不过，来自肺脉的血不含氧。

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

在肺脉上。导线的作用就像脏上的永久性划片。

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

血从左室流脉，以及从右室流肺脉。

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

注意，这条大脉确实会分成脉和肺脉。

Remember how fluid buildup increased pressure in the pulmonary artery?

还记得体积聚如何增加肺脉压力吧？

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

大脉指的就是这两条把血脏的要脉：脉和肺脉。

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

肺脉将脱氧血从脏输送到肺。

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，可见脉来自于左室，肺脉来自于右室。

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，患者右室和肺脉的氧饱和度就升高了。

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

肺脉携来自于右室的低氧血，而肺静脉将来自于肺的富氧血运至左房。

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脏通往肺部、携缺氧血的肺脉中。

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

脏左侧的最高点应为脉弓，下面是肺脉。

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

接着，血从右房进右室并被泵肺脉，最终进肺。

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

如果脉和肺脉这两条大脉不分开的话，你就会有这条从室发出的大脉。

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.

一旦血通过肺脉瓣，便会进肺脉；肺脉将血从脏输送到左肺和右肺。

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.

血从肺脉进较细小的肺小脉，最后进毛细血管。

When the ventricle contracts, blood is pushed into the short pulmonary trunk before branching toward each lung through the right and left pulmonary arteries.

室收缩时，血在通过右肺脉和左肺脉向每个肺分支前被推短肺干。

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指大血管" Great vessels" ，包括了上腔静脉、下腔静脉、升脉、脉弓、肺脉与降脉。

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-大脉转位，即L-TGA，左旋的意思是脉要位于肺脉的左侧。

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.

右室通过肺半月瓣将血泵肺脉干，肺脉干只是一个大血管，它分裂形成左右肺脉。
